Ok, next patch. After I corrected dbgcom.c, gdb didn't crash trying the
command p *(short *)-1, instead it prints something that must be bogus
as the memory in question is unavailable:
(gdb) p mnt
$1 = (struct mntent *) 0xffffffff
(gdb) p *mnt
$2 = {mnt_fsname = 0xfffffff0 "\200Y\022", mnt_dir = 0x2e29544e "\200Y\022",
mnt_type = 0xa "\200Y\022", mnt_opts = 0x0, mnt_freq = 0,
mnt_passno = 353984, mnt_time = 0}
Here's a patch to correct this. Who should I send this to? Robert Hoehne?
Delorie?
Thanks,
MartinS
