1.1.1b crash (RUN_ONCE problem?)

[Norm Green]

I'm debugging a failure in a debug build on Solaris SPARC in the below 
code in rand_lib.c.  On line 744, rand_meth_lock is NULL, which suggests 
the RUN_ONCE code is not working.  Wondering if anyone else has seen 
this problem?
We did not see this issue in 1.1.1a.  Perhaps changes in the RUN_ONCE 
code in this commit are responsible?
