Subject Re: A bug with httpd-2.4.2 Win-x64
Date Wed, 18 Apr 2012 00:23:14 GMT
Hi Stefan,

I tried many possible ways, and only found this clue for now:

	/* main.c, line 707 */
			==>  unload_module(void *data)  
					==>  ap_remove_module(module *m)  
							==>  free(ap_module_short_names[i] ) 
									==>  HeapFree(_crtheap, 0, pBlock); 
										 /* bad pointer: pBlock */

It always happens with the Debug config of the VS2010 x64 platform setting, not with the Release
version, or both of the VS2008(VS9) x64 builds. 
BTW, I converted the project files in this way:
	Apache.dsw + *.dsp ==> Apache(VS9).sln + *.vcproj ==> Apache(VS10).sln + *.vcXproj

I can't see anything wrong with that code. I fear the heap corruption happens at some other
place and it is coincidence that it is detected here. Are there any additional heap consistency
checks that you can switch on?
