>Description:
When using sysintall(8), it crashes while "probing devices".
I've tracked down the problem to libdisk(3) and it appears that it crashes while getting disk info on my ada0 disk.
This is reproductible by using the libdisk test suite in /usr/src/lib/libdisk (tst01.c).
tst01 ada0
Gdb:
Starting program: /usr/src/lib/libdisk/tst01 ada0
Program received signal SIGSEGV, Segmentation fault.
0x08063032 in L1 ()
(gdb) bt
#0 0x08063032 in L1 ()

#2 0x0804bd8c in Int_Open_Disk (name=0xbfbfea1b "ada0", conftxt=Variable "conftxt" is not available.

#4 0x08048438 in main (argc=Variable "argc" is not available.

Please tell me if you need more information.
Thanks, regards.
