  The GCC build used 4.4.2.
  GDB is available on this system; is there any information I can provide
  to help track this down?
This needs to be isolated with a debugging session.  It does not happen
on non-osf systems.

I think this is one of three things:

1. A bug in the old osf C library
2. A bug in the shared compilation tools, e.g. the assembler
3. An allocation bug in GMP.

I think (1) is the most likely.

You might want to try a few things:

Build with ".../configure CFLAGS=-g" to disable optimisation and enable
debugging.  If the failures remain, gdb will work better.

You might also try with --build=none to disable assembly code.  That
will give some indication of cause (2).
