No fork() in the first zipfile I looked at (from [1] in comment 2), and unless the globals use something inter-process such as semaphores or file locking, there is no way they should interfere with globals in other processes. Using RTLD_GLOBAL, exceptions or RTTI doesn't change the fact that processes have their own memory space. > Try crypto++ 5.6.0 (which _had_ global objects) located at > http://www.cryptopp.com/cryptopp560.zip.

Ah, I tried that stress test against 5.6.1 as that's what my distro provides. That stress test *does* use fork, but didn't crash for me. If I get time tomorrow I'll try it against 5.6.0 I'm probably taking this enhancement request waaaay off-topic, I just want to convince myself you're not wasting time asking for a warning that won't help prevent user error
