I came across this bug, too, finally trying the gb.map example.

The same situation for me and additionally, I get a signal #6 when
(slowly step-by-step) scrolling too deep into the map. It comes from an
assertion which states:

gbx3: malloc.c:3621: _int_malloc: Assertion `victim->fd_nextsize->bk_nextsize == victim' failed.

Sebastian, maybe you should carry this to gambas-user?
