a {{{ KDL PANIC: Invalid concurrent access to page 0x82a87348 (start),
currently accessed by: 6 }}} occured within seconds of starting jam -aqj3
@alpha-raw
After several 'co', Haiku recovered.
backtrace attached.

Comment(by mmadia):
In the same session of Haiku, I've reproduced it about 5 times. Looking
at jam -dx -aqj3 @alpha-raw, the kdl occurs after a gcc command -- as
opposed to ar: or ranlib.
