I haven't reproduced this one, but we do have an example of GHCi
crashing which I was intending to investigate today (I was, until our
file server went out to lunch again... grrr.).   With any luck, these
two are the same bug, though.

This is a known problem, for which we haven't managed to find a good fix
for yet.  Compiling with -O is the only workaround, I'm afraid.
