Please attach preprocessed source on which the compiler crashes and all compiler
flags used and also state which exact gcc you are using.
RHEL3 gcc driver is trying to reproduce internal compiler errors and if it
manages to reproduce them, it will prepare all the info for you in some
/tmp/cc*.out file mentioned in the error message.  If it hasn't created it,
please look at http://gcc.gnu.org/bugs.html instructions how to prepare the
requested info and then file it here.
Without the preprocessed source there we can't do anything easily, as the
compiler crash might depend on the exact version of all headers the sources
are using and exact version of the source plus perhaps configuration stuff.
Thanks.

Please reopen if you create a self-contained testcase we could look at.
