Apparently, yes. Though I also have weird "xalloc" failures before that 
(although more rare).

I don't know what exactly is going on, but I've build everything with -O0 -ggdb 
and yet cannot get a decent stack trace (maybe there are some hardcoded flags 
on the makefiles or whatnot). I didn't spent too much time on it however.

Since I'd like to investigate more on this issue, what your suggestion would be 
to dig deeper into the issue?
