Bug#855095: gcc-6: [hppa] regression: trivial program segfaults
Package: gcc-6
Version: 6.3.0-6
Severity: important
Control: affects -1 ffmpeg
X-Debbugs-Cc: debian-hppa@lists.debian.org
Dear Maintainer,
ffmpeg 7:3.2.4-1 failed to build on hppa, because configure's C compiler test failed [1]:
BEGIN /tmp/ffconf.JlfWXo0F.c
1 int main(void){ return 0; }
END /tmp/ffconf.JlfWXo0F.c
gcc -Wdate-time -D_FORTIFY_SOURCE=2 -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -Wformat -Werror=format-security -fno-strict-overflow -fstack-protector-all -fPIE -c -o /tmp/ffconf.vzRvJxAo.o /tmp/ffconf.JlfWXo0F.c
cc1: warning: -fstack-protector not supported for this target
gcc -Wl,-z,relro -Wl,-z,now -fPIE -pie -o /tmp/ffconf.lZtBYrZt /tmp/ffconf.vzRvJxAo.o
Segmentation fault
It looks like gcc miscompiles the most trivial program, so that it segfaults when run,
but gcc-6 6.3.0-3 worked fine three weeks ago [2].
Best regards,
Andreas
