[Bug gcov/profile/24093] New: cgraph exhausts virtual memory building 197.parser with -profile-use -O3

["janis187 at us dot ibm dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Beginning with mainline from 2005-09-25, GCC dies with "virtual memory
exhausted: cannot allocate memory" when building the SPEC CPU2000 test
197.parser with -O3 and -fprofile-generate/-fprofile-use.  In my parallel
build of 197.parser the failures are for fast-match.c, build-disjuncts.c,
and post-process.c, using GCC for powerpc64-linux with -m32.  The rest
of the CPU2000 programs build and run successfully using the same
options.  I saw this on two systems where I do lots of testing and have
never run out of memory before, so it's not just that my memory size is
unreasonably small.

Function cgraph_clone_inlined_nodes is in the traceback for the abort.
There are two cgraph changes from Jan Hubicka on 2005-09-24 that seem
to be likely suspects.
