[Bug c++/32290] New: GCC crashes with OOM when compiling trivial source file (no endless loop)

["aribrei at arcor dot de" <gcc-bugzilla at gcc dot gnu dot org>]

This is the output of a valid 60 line source file compile. The preprocessed
source is 30 KB in size and I know that there are no cycles in the code.
