Package: libc6-prof
Version: 2.17-92+b1
Followup-For: Bug #589755
The bug is still present as of 2.17-92+b1. It is actually possible to
trigger it even using a minimal source program:
int main() {
return 0;
}
Compiling following the instructions in README.Debian fails:
$ gcc -g -pg main.cc -static-libstdc++ -lc_p
/usr/bin/ld: dynamic STT_GNU_IFUNC symbol `strcmp' with pointer equality
in
`/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../x86_64-linux-gnu/libc_p.a(strcmp.op)'
can not be used when making an executable; recompile with -fPIE and
relink with -pie
collect2: error: ld returned 1 exit status
Adding `-static -Wl,--no-export-dynamic' to the command line fixes this:
$ gcc -g -pg main.cc -static -Wl,--no-export-dynamic -static-li
bstdc++ -lc_p
However:
$ gdb ./a.out

I can provide more information if needed.
