Subject: Re:  New: gengtype core dumping on Origin with MIPSpro 7.4

This is a known bug in SGI's MIPSpro C 7.4: it provides a built-in version
of memcmp, and miscompiles it under some circumstances.

There are a couple of possible fixes/workarounds:

* Upgrade to MIPSpro C 7.4.1m (only available on CD-ROM from SGI).

* Disable the memcmp intrinsic in /usr/include/internal/string_core.h:

* Disable all intrinsics for the bootstrap by configuring/bootstrapping
  with

  CC='cc -U__INLINE_INTRINSICS'

I'll document all this in the installation notes once I get to it.
