I am working on a Sun Solaris 2.8 machine. It comes with Sun C compiler cc (5.5, 2003/03/12). Using this cc, I was able to compile gcc 4.4 20081107. However, I was experiencing some stability issues with it. For example, valid fortran code was producing internal compiler errors http://gcc.gnu.org/ml/fortran/2009-01/msg00178.html . So, I tried updating gcc 4.4 20081107 to gcc 4.4 20080109. Bootstrapping gcc 4.4 20080109 from Sun's C compiler works. But bootstrapping gcc 4.4 20080109 from gcc 4.4 20081107 fails with an internal compiler error http://gcc.gnu.org/ml/gcc-help/2009-01/msg00109.html . Could someone please tell me how to debug the problem further? How does one go about debugging "internal compiler errors"? I have access to dbx but no gdb.
