Re: [PHP-DEV] Re: [imp] IMP 3.1 segfault
You should report this to the PHP team. Perhaps it's even fixed in PHP 4.2.3.
Zitat von Iain [EMAIL PROTECTED]:
Hi,
I seem to have found a work around for this. I recompiled the PHP4 debian
packages with the option:
export DEB_BUILD_OPTIONS=debug nostrip
which is equivalent to --enable-debug and not stripping the binaries.
Anyway after installing the new packages the bug mysteriously
dissappears.
Very unsatisfying :(
hope this helps someone else.
Iain.
