[En-Nut-Discussion] Bug in timer.c?

[Ole Reinhardt]

Hi all,

while hacking on my rfcomm code I struggled over a bug in the timer
handling.

rfcomm uses a oneshot timer.

I use the unix emulation, but I suppose this also could happen with the
avr code?

That the gdb output:

[rfcomm-cmd]$inquiry sync
Starting sync inquiry for 5 sec:
Devices: 1
Device         bt_addr cod        RSSI
[0]: 00:02:72:40:42:b0 0x003e0100 0
[rfcomm-cmd]$rfsession 0 1
RFCOMM connect to 00:02:72:40:42:b0 Channel 1
L2CAP:Created connection for handle: 1 at index 0
RFCOMM: L2CAP connect . Unique handle: 0021

Program received signal SIGSEGV, Segmentation fault.

Anybody knows more about this bug?

I use the latest code from CVS (btnut and NutOS as well)
