You must tell GDB to ignore SIGSEGV signals and pass them on to Fiasco-UX.
The following at the GDB prompt will do:

handle 11 nostop noprint

Of course you could also do this from .gdbinit. Note that when using Fiasco-UX
with GDB you'll lose the ability to use Fiasco's built-in debugger JDB as
SIGTRAP is used by GDB.
