It's trying to protect the new stack for the thread, which is obviously in the wrong spot. The new stack is in the middle of the last threads guard. I don't know what conditions triggered here, but I'm tracking it down. The C library has a stack cache which might be the culprit, but I'd believed all these issues fixed, I guess not. I like easy bugs... this is simply a matter of debugging at this point. >>> I submitted a patch to return an error if but there was no comment. >> >> Reference? >> > http://www.spinics.net/lists/linux-parisc/msg03352.html Interesting.
