I'm not able to create script reproduce segfault (yet), but this 
script cause memory leak with APC. It does not leak memory first 
time loaded, but it leaks memory from second time. PHP does not 
leak memory without APC.

Fixing this problem may fix segfualt...

I also send this mail to Japanese PHP Developer list, since it 
seems this problem is related to mbstring module.
