Bug#317233: gcc-4.0 regression, possibly powerpc-specific, causes segfault in compiled binary
Package: gcc-4.0
Version: 4.0.0-11
Severity: normal
If I compile schroot
http://ftp.debian.org/debian/pool/main/s/schroot/schroot_0.1.2-1.dsc
http://ftp.debian.org/debian/pool/main/s/schroot/schroot_0.1.2.orig.tar.gz
http://ftp.debian.org/debian/pool/main/s/schroot/schroot_0.1.2-1.diff.gz
with gcc-3.3 and gcc-3.4, the resulting binary works. If I build with
gcc-4.0, it segfaults. Try "schroot --help", for example.
The problem only because apparent when the gcc-defaults changed to
default to 4.0.
I've tried compiling with nearly every gcc warning enabled, but I
couldn't find anything other than trivial warnings. I've also reviewed
the code, but can't see anything wrong. The code is fairly simple;
I'm not using any GCC extensions, just plain C99 source.
The fault occurs shortly after startup, calling parse_options()
(schroot/schroot.c).
If it would be useful, I can reduce it to a smaller test case, but the
code worked just fine with 3.3.
Regards,
Roger
