cd /usr/src/release/sysinstall
CC="gcc -g" make all
./sysinstall
[list the exacts steps you took, so I can reproduce it too, or find that
I can't :)]
(core dump)
gdb ./sysinstall sysinstall.core
Usual procedure here (backtrace, etc). The problem will most likely be
the member of a structure pointed by a NULL pointer being reference. Eg,
mediaDevice->shutdown(...), i->kids.
It would help further if you then break-pointed the function where the
problem happened, and stepped through it to pinpoint when the variable
turned to NULL (eg, mediaDevice->get(mediaDevice, ...)).
