[Bug c/32266] New: Excessive memory usage (805M!)

["jsberg04+computing dot bugs dot gcc at ftml dot net" <gcc-bugzilla at gcc dot gnu dot org>]

I will attach the example in a subsequent comment.  If I execute:

gcc -O1 -c xf86ScanPci.c

it sucks up 805M of virtual memory.  No optimization, no problem.

gcc -v
