I got the following from a user...
He's (forced to) use FreeBSD 8
Is this still an issue? and does anyone have thoughts?

-------------------------

Hi Julian,
I have a set of code with a fairly strong unit test framework. This 
framework works on Windows (cygwin) and Linux amongst other 
platforms.  While running tests I always verify all allocated memory 
is freed for good hygiene.

I've been running a test which has a printf in it and the following stack:
#3  0x0000000000405219 in calloc (count=1, size=80) at testrunner.c:642
#4  0x0000000806bd1ce4 in pthread_mutexattr_init () from /lib/libthr.so.3
#5  0x0000000806bd1f91 in pthread_mutex_getyieldloops_np () from 
/lib/libthr.so.3
#6  0x0000000806bd2b81 in pthread_mutex_lock () from /lib/libthr.so.3
#7  0x0000000806dcda13 in abort () from /lib/libc.so.7
#8  0x0000000806dcdab3 in abort () from /lib/libc.so.7
#9  0x0000000806dc91b9 in getenv () from /lib/libc.so.7
#10 0x0000000806dc37ae in open () from /lib/libc.so.7
#11 0x0000000806dc50ca in vfprintf () from /lib/libc.so.7
#12 0x0000000806db10fa in printf () from /lib/libc.so.7


This calloc'd memory never gets freed and forces my unit tests to fail.

I know this is an extremely old version of FreeBSD, but I figured I'd 
let you know so that perhaps somebody, somewhere, might be interested 
in such things and get a hold of the stack trace.
