Thanks for the precise bug report.  This makes it easier to debug GPC.

I don't know how long it took you to find that place, but GPC has a
debugging option `-dY' to dump the source to `stderr' during compilation.
Using this, you immediately see the location where GPC crashed.

The bug, however, seems to be somewhat harder ... working on it ...
