The attached example seems to work. I put it in the top-level directory
of the (built) openssl tree and compiled with;
gcc -Wall -Iinclude -o foobar foobar.c -L. -lcrypto
The output shows that dynamic lockids are negative;
About to test
Created lock 'dyn_lck.c:257'
Created lock 'dyn_lck.c:257'
Got new locks -1, -2
Doing mode 9 lock on 'dyn_lck.c:257' from foobar.c:47
Locked the lock
Doing mode 10 lock on 'dyn_lck.c:257' from foobar.c:49
Unlocked the lock
Destroying lock 'dyn_lck.c:257' from dyn_lck.c:329
Destroying lock 'dyn_lck.c:257' from dyn_lck.c:329
Destroyed the locks, DONE
Perhaps that'll help distinguish what's going on in your code?
Cheers,
Geoff
