Package: gcc
Version: 4:4.7.2-1
Severity: important

gcc cannot compile programs in amd64 with the -fPIE and -pie security flags. It seems that crt1.o is not compiled with -fPIC. I tested this with the "transmission" package:

Flags used:

export CFLAGS="-pipe -O2 -fPIE"
export CXXFLAGS="${CFLAGS}"
export LDFLAGS="-Wl,-pie"
./configure

Terminal output:

checking whether the C compiler works... no
configure: error: in `/home/riley/Desktop/transmission-2.77':
configure: error: C compiler cannot create executables
See `config.log' for more details

Relevant content in config.log:

configure:3759: checking whether the C compiler works
configure:3781: gcc -pipe -O2 -fPIE  -Wl,-pie conftest.c  >&5
/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/4.7/../../../x86_64-linux-gnu/crt1.o: relocation R_X86_64_32S against `__libc_csu_fini' can not be used when making a shared object; recompile with -fPIC

Which is expected. Scrt1.o should be used instead.

You should not try to override linker flags, but instead teach gcc to
pass the correct flags. You should pass '-pie' to gcc instead of
'-Wl,-pie'.

Closing the bug.
