Hi!
I have no idea if this problem is Apache2 related or PHP related.
Running current CVS of both.
I have no single script to reproduce this, but i have the same
problem with older versions of PHP too, haven't tried with older apache
version thou.
And I don't know if this is the correct way to debug apache, but here's
the output from gdb.
Program received signal SIGPIPE, Broken pipe.
