[Bug debug/33868] New: [4.3 Regression] Gross memory usage of var-tracking

["rguenth at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The glibc testsuite runs into a var-tracking issue where we consume loads of
memory (>2GB) to compile test-tgmath2.i.  Probably related to PR31412.

./cc1 -O -o /dev/null test-tgmath2.i -std=gnu99 -fgnu89-inline
-fmerge-all-constants -fno-builtin -g
