This is a bad interaction between compiler and library. -Os does not inline all cases and we need those inlined. I advise to use the default compile flags. OK, will try -O2 then. Thanks for the help! I know this is marked as WONTFIX, but just for reference, this can be fixed so it does compile with -Os, simply by unapplying this commit: http://sourceware.org/cgi-bin/cvsweb.cgi/libc/io/sys/stat.h.diff?r1=1.56&r2=1.57&cvsroot=glibc |
