Have you done any large builds? (linux kernel size or bigger) Hardware
  problems often do not show up for installs and small builds.

Yes. egcs and gcc were merged to become the current gcc. See gcc.gnu.org
  for more info.

I believe redhat uses egcs-2.91.66 because gcc-2.95.2 uses a different ABI
  for C++ programs, and redhat did not want an ABI breakage, even if it
  only affected C++ programs.

I did it by building gcc 2.95.2 with egcs-2.91.66 . If you get sig11 while
  building gcc 2.95.2 with egcs-2.91.66, you probably have a hardware
  problem.

Note that gcc 2.95.x and egcs-2.91.66 have different C++ ABIs (due to an
  MI bugfix, I belive). So you must ensure that all parts of a C++ program
  are built with the same compiler. (this does not affect C.)
