809964 - Assertion failure: count.numLocks >= count.numHidden, at /home/mikeh/dev/mozilla/btg014/gecko/hal/HalWakeLock.cpp:118

Status: RESOLVED DUPLICATE of bug 809671

(Firefox OS Graveyard :: General, defect)

Description

[Mike Habicher [:mikeh] (high bugzilla latency)]

Observed on Otoro builds: during start-up, logcat shows:

F/MOZ_Assert(  106): Assertion failure: count.numLocks >= count.numHidden, at /home/mikeh/dev/mozilla/btg014/gecko/hal/HalWakeLock.cpp:118
F/libc    (  106): Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1)

This is because in DEBUG builds, the assertion failure (intentionally) throws a SIGSEGV to cause a process abort.
