do we consider extravagant memory usage a gcc bug?

Trying to build qemu on a beagle board:

CC sparc64-linux-user/translate.o

cc1: out of memory allocating 26975704 bytes after a total of 70742016 bytes

# ls -lh target-sparc/translate.c -rw-r--r-- 1 root root 191K Jan 31 12:05 target-sparc/translate.c

ie gcc wants (at least) 100M of RAM trying to compile a 190K sourcefile. (and probably more overall since the board has 500MB RAM total and it hit the out-of-memory condition).

This seems a bit excessive to me, but do we consider it enough of a bug to be worth looking into?

(I believe this source file has caused compile failures on the buildds too, which have rather more RAM/swap than my beagle.)
