Strange segfaults during PHP emerge - during .configure phase I believe...

tanstaafl-2
Anyone ever seen/can explain these?

I had 3 of them, again, apparently during the .configure phase:

Everything seems ok now after the update...

Weird...

Yes, I have seen them all the time on multiple boxes. AFAIK this is
perfectly normal behavior, I think it comes from autoconf trying -- on
purpose -- to find broken configuration options so it knows what to
avoid.

Ok, cool, thanks Paul. It was the first time I'd seen them, so its
reassuring that I'm not alone...

Would be good to be documented somewhere though...

Thanks again
