Hi, this time all crashed again during make build.
This is the error displayed:

uvm_fault(0xf4923e70,0x2a74c000,0,3) -> 1
kernel: page fault trap, code=0
Stopped in ccp at 	_bremfree+0x4b: movl	%eax,0x14(%edi)

This time on your request i typed trace and wrote all down (man... lot of
writing).
Here it is:

Well, this is what the debugger gave me, i hope i wrote everyting down
correctly, first i had to write down the things on paper and then from
paper in this mail, so maybe there are some errors in it, but i am not
sure, hope not.
The rest of the system hang and with the command reboot in the debugger he
gave up and i had to press the reset button.
Hope this gives you enough information.
Oh yes... it keeps crashing now, so make build keeps crashing.... no way i
can do it anymore.
Not even after i removed the complete /usr/src dir and got all source
again with sup.
Plz advice what to do now.
Bye,

Reinoud.
