That part is a bug.  bash should check for memory allocation errors.
It seems to do so, but not perfectly:

$ softlimit -m 8000000 bash -c 'function xxx { xxx; }; xxx'
bash: xmalloc: subst.c:5518: cannot allocate 112 bytes (0 bytes allocated)
$ softlimit -m 16000000 bash -c 'function xxx { xxx; }; xxx'
Segmentation fault

Of course, the bug might be in some underlying library code, not in
bash itself.
