php bombs Apache in large class

[ronman]

Hi,
I've got a legacy class (1600 lines!) that I'm coding the methods for, and it crashes Apache in strange places, usually having to do with a call to a function, either $this->someFunc() or even native functions like mktime() or abs().

I increased the memory_limit parameter in php.ini from 8M to 32M.
PHP is running as a module.
The error reported by Apache is a page fault in php4ts.dll.
Everything runs under Win32.
This is a system I've used for over a year with no problem, and other scripts work fine, so I don't think it's an installation problem.

Help!?

Thanks,

One more thing:
php4ts.dll also bombs with the same page fault when running from the command line, without Apache running at all.
