[Bug gdb/9949] Ctrl-C reboots host

/root# cat /proc/version
Linux version 2.6.27.10 (root@bob) (gcc version 3.4.3) #1 SMP Tue Jan 6 
14:57:01 GMT 2009

Its now been narrowed down to a developer running a different toolchain, 
although all the packages in the toolchain are the same versions as the one 
that works fine. Its still strange that it manages to reboot the system though.

It seems to me that this must be a kernel problem.
Can you try other versions of the kernel?
Do you see anything in your system logs?
