>Description:
        I was compiling a port (tor-browser) when the system decided to stop
        because the CPU was overheating.

Here is the result of the show panic, show registers, trace, and ps
commands :

After that I typed :
ddb{0}> boot dump
dumping to dev 4,17 off 492583
dump

But the system froze and I had to reboot it manually.

Though it isn't the first time my computer had to reboot because it was
overheating (I was testing the stress(1) package), it is the first time
it crashed like this.

Is there anything I can do to help debug this? Is it debugable? It is
worth spending time to debug it?

Best,
