Apache crashes when stopped or restarted with php4_module loaded.

'The instruction at "0x0193450a" referenced memory at "0x00000000". The memory could not be "written".'

Upon entering the debugger: 
'Unhandled exception in Apache.exe (PHP4TS.DLL): 0xC0000005: Access violation.'

First couple of lines from the debugger window:
0193450A   mov         dword ptr [ecx],edx
0193450C   mov         eax,dword ptr [esi]
0193450E   test        eax,eax
01934510   je          01934518
01934512   mov         ecx,dword ptr [esi+4]
01934515   mov         dword ptr [eax+4],ecx
01934518   push        esi
01934519   call        dword ptr ds:[196B1C8h]
0193451F   mov         eax,[0199CD08]

No PHP modules, default php.ini-optimized, latest snapshot of Apache 1.3 CVS tree.

BTW, it's the same on another computer running NT4 SP5

this seems to be actually an Apache problem: see http://marc.theaimsgroup.com/?l=apache-new-httpd&m=98271643321404&w=2
