Comment (by ttcoder):
The `debugger("oops")` issue (it is indeed ''this'' ticket that tracks it,
right?) has taken a sharp turn for the worse for me.. Appeared on this
laptop last week, but I could get away with a reboot.. But with today's
update to hrev48168 I can't possibly play much media at all without
crashing media_addon_server with the "oops" tripwire.. (or sometimes the
segmentation fault in float_to_float, making me think that maybe it's the
mixer that's corrupting something in the address space of the server).
Before getting into more involved stuff, a question.. I once got the "low
resource" warning in the syslog right before the crash, at boot time when
obviously there were no resources being wasted:
{{{
DAEMON 'DHCP': /dev/net/broadcom570x/0: DHCP status = No error
KERN: low resource memory: normal -> critical
KERN: low resource memory: critical -> normal
..
KERN: 605: DEBUGGER: oops
KERN: debug_server: Thread 605 entered the debugger: Debugger call: `oops'
}}}
So my question is.. What can trigger a `low resource memory: normal ->
critical` warning, apart from genuine resource waste?
An add-on going into an infinite loop doing malloc() ? An add-on going in
an infinite loop reading "wild" memory outside of its own memory bounds ?
Bonus question -- are there open Coverity CIDs on MediaAddonServer.cpp and
friends ?
