Re: test008 failed in HEAD

If you are using gcc, it might help to compile BDB and/or OpenLDAP without -O and see if that helps. The gcc mailinglist and comp.programming.threads recently discussed a some gcc optimizations that are invalid for threaded code. E.g. gcc can turn things like

<static or extern> int v; ... if (set_v()) v += 1; into flag1 = (set_v() != 0); reg2 = v; reg2 += flag1; v = reg2;

If set_v() does trylock(lock protecting v) and returns true at success, this breaks thread safety when set_v() fails.

The optimization is valid as far as the C standard is concerned, but POSIX forbids it for threaded code. Otherwise one would have to sprinkle 'volatile' all over a threaded program, to protect it from the compiler.
