Re: gcc 3.2 on Solaris 8 (libgcc_s.so problem)



Ah, I see it:
http://gcc.gnu.org/ml/gcc-bugs/2002-05/msg00560.html
http://gcc.gnu.org/ml/gcc-bugs/2002-08/msg00348.html

Are you sure these are the 32 bit libraries? I tried just moving them into local/lib, but libgcc_s.so.1 segfaults instantly.

I tried this:

int main(void)
{
return 0;
}

When I debug it in gdb I get this:

Program received signal SIGSEGV, Segmentation fault.

83 ob->tbase = tbase;

This is a known problem: PR target/6668, but unfortunately still not fixed.
