I'm not clear on the action item here? What do you need tested?
Background:
~~~~~~~~~~
The locked state of a lock is 0 on hppa, which means that if you don't
initialize your locks (as documented), they begin in the locked state
e.g. bss initialized to zero.
You must use PERL_SYS_INIT3() on hppa, I don't know how it worked without it.
As hppa porters we spend a lot of time tracking down uninitialized
locks (or memset'd 0 locks), which just happen to work on every other
architecture.
Note: As of the NPTL port for hppa, we consciously changed this to
match all other architectures e.g. unlocked is zero.
Cheers,
Carlos.
