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?
