[Deepesh Rajan]

Hi All,

>From the bug 29925 from the following link
https://sourceware.org/bugzilla/show_bug.cgi?id=29925

I was trying to reproduce the issue on binutils 2.36 .



steps for reproducing the issue:

   1. git clone git://sourceware.org/git/binutils-gdb.git
   2. git checkout binutils_2_36
   3. CC="clang -fsanitize=address" CXX="clang++ -fsanitize=address"
   ./configure --disable-shared && make -j$(nproc)
   4. ./binutils/nm-new -A -a -l -S -s --special-syms --synthetic
   --with-symbol-versions -D poc



*but while doing make getting the below errors :*



*==489551==WARNING: invalid path to external symbolizer!*

*==489551==WARNING: Failed to use and restart external symbolizer!*

We’ve not seen the above errors by using the binutils tar file.

And, the same errors were seen with latest binutils upstream sources.


1. Why we are seeing these errors only with upstream git sources.

2. Is this issue applicable for older versions on binutils (2.36)?

3. Is this issue with any specific version of clang (we are using 14.0).

4. The bug Target Milestone 2.40, says fixed in 2.40 but we could still
reproduce the issue on 2.40 (we’ve checked the fix patch is present in
sources) and could not reproduce in 2.42. In which version the issue is
fixed?



Thanks in advance.

Deepesh
