Pre-request: *important*: Install latest Wine Staging (1.7.53) on Linux. I'm using 32bit Ubuntu 15.10 with Linux kernel 4.2.0-16-generic. Wine Staging is an official part of Wine, installation steps refer to https://github.com/wine-compholio/wine-staging/wiki/Installation Steps to reproduce: 1. Install MSYS2 on Wine 1) *important*: MSYS2's installer works mostly out of box on Wine Staging today, except a few workaround is needed: $ export STAGING_WRITECOPY=1 2) download MSYS2 installer from https://msys2.github.io/ http://repo.msys2.org/distrib/i686/msys2-i686-20150916.exe 3) install on Wine: $ mv ~/.wine ~/.wine.bak $ wine msys2-i686-20150916.exe The installer should work out of box just like on Windows. Refer to http://sourceforge.net/p/msys2/wiki/MSYS2%20installation/ for additional introduction for usage of MSYS2 on Windows, it is the same for Wine. 4) install toolchain on MSYS2: Start a MINGW32 shell: $ cd ~/.wine/drive_c/msys32/ $ wine start mingw32_shell.bat Inside the MINGW32 shell in mintty terminal: $ pacman -S --noconfirm base-devel mingw-w64-i686-toolchain This will install gcc / bintuils / make and other tools for compiling Win32 software. Refer to http://sourceforge.net/p/msys2/wiki/Contributing%20to%20MSYS2/ for additional information. Note that currently MSYS2 provides binary package for binutils 2.25.1, but I can also reproduce the same ld crashing bug with latest binutils compiled by myself. 2. Build MinGW xz package on MSYS2 (inside MINGW32 shell on Wine): 1) firstly clone MINGW packages PKGBUILD files: $ git clone https://github.com/Alexpux/MINGW-packages.git (If git is not installed, try `pacman -S git`) 2) cd to the directory of xz: $ xd MINGW-packages/mingw-w64-xz 3) use makepkg-mingw to compile xz package: $ makepkg-mingw -f -s --skippgpcheck --noconfirm This will download the xz source code and build dependencies for xz then build the xz package. Refer to http://sourceforge.net/p/msys2/wiki/Contributing%20to%20MSYS2/ for additional information. Expect result: Build the xz package successfully. Actual result: ld crashes when linking lzmadec.exe (sorry, my #comment 1 is wrong, not crashing for xzdec.exe, but for lzmadec.exe) collect2 reports: collect2.exe: error: ld returned 5 exit status Command line below: /bin/sh ../../libtool --tag=CC --mode=link i686-w64-mingw32-gcc -Wall -Wextra -Wvla -Wformat=2 -Winit-self -Wmissing-include-dirs -Wstrict-aliasing -Wfloat-equal -Wundef -Wshadow -Wpointer-arith -Wbad-function-cast -Wwrite-strings -Wlogical-op -Waggregate-return -Wstrict-prototypes -Wold-style-definition -Wmissing-prototypes -Wmissing-declarations -Wmissing-noreturn -Wredundant-decls -march=i686 -mtune=generic -O2 -pipe -pipe -o lzmadec.exe lzmadec-xzdec.o lzmadec-tuklib_progname.o lzmadec-tuklib_exit.o lzmadec_w32res.o ../../src/liblzma/liblzma.la -L/mingw32/lib -lintl libtool: link: i686-w64-mingw32-gcc -Wall -Wextra -Wvla -Wformat=2 -Winit-self -Wmissing-include-dirs -Wstrict-aliasing -Wfloat-equal -Wundef -Wshadow -Wpointer-arith -Wbad-function-cast -Wwrite-strings -Wlogical-op -Waggregate-return -Wstrict-prototypes -Wold-style-definition -Wmissing-prototypes -Wmissing-declarations -Wmissing-noreturn -Wredundant-decls -march=i686 -mtune=generic -O2 -pipe -pipe -o .libs/lzmadec.exe lzmadec-xzdec.o lzmadec-tuklib_progname.o lzmadec-tuklib_exit.o lzmadec_w32res.o ../../src/liblzma/.libs/liblzma.dll.a -L/mingw32/lib -lintl -L/mingw32/lib Backtrace below: (note I'm not sure I can reproduce this bug with debugging build of binutils, but I'll try harder again) Unhandled exception: page fault on read access to 0x013e0038 in 32-bit code (0xb744af83).

Backtrace: ld crashes, with debugging symbol, compile with -g -O2 -gdwarf2 -gstrict-dwarf
Hi, this is a backtrace with debugging symbol, ld from git HEAD, compiled with "-g -O2 -dwarf2 -gstric-dwarf". I'll try further with a build of -O0, but I remember it doesn't crash last time when I was testing. Anyway it worth try again.
I upload a compressed directory of xzdec/ , which includes all object files to reproduce this bug: https://drive.google.com/file/d/0BxjsxTbiBaUHYmtQQkdiZlp0T1U/view?usp=sharing I'll try to investigate how to reduce the test case size. When running ld on Wine with Valgrind, Valgrind reports some invalid read which seems related to this bug. Additional information here: https://sourceware.org/ml/binutils/2015-10/msg00058.html Once I can reproduce same valgrind error report with latest binutils, I'll copy them here. (No time right now, sorry) (In reply to Qian Hong from comment #7) > When running ld on Wine with Valgrind, Valgrind reports some invalid read > which seems related to this bug.

(No time right now, sorry) Update: this time valgrind doesn't report anything related to this bug for me. BTW, I'm @fracting in freenode #gdb irc channel, I'm glad to provide more information either here or at irc if required. I'm still hoping to reduce the size of test case, but no time to do that right now. |
