Re: new[]/delete disparity in some OpenGL code?



Sam,

Overriding the global new and delete operators I'm afraid I've seen lots of situations like this --although in Tiger (haven't received Leopard yet).
The mismatch between new[] and delete seems indeed to occur quite often in the system libraries, but obviously I wouldn't know where...


Sorry,
Dario

When I call aglDestroyContext as part of my shut down, our memory debugging is getting triggered in a number of places where it spots that an allocation has been made with new[] but is getting disposed with delete (as opposed to delete[]).

Has anyone else see similar behaviour? A typical call stack is...

#4 ... my memory debug code here...
#5	0x0012687b in operator delete at memory_manager.cpp:710
#6	0x969a80c9 in BindingTable::~BindingTable
#7	0x969ae1cf in TGenericLinker::~TGenericLinker
#8	0x9696b7ec in ShDestruct
#9	0x17ec9647 in gleFreeProgramObject
#10	0x17dc3861 in gleReleaseSharedState
#11	0x17dc2383 in gliDestroyContext
#12	0x91041463 in cglDestroyContext
#13	0x910410f1 in CGLDestroyContext
#14	0x917a571b in aglDestroyContext
#15 ... my cleanup code here...

The annoying thing is that this code is presumably in a library, so I can't do anything about it - but I don't really want to turn off my memory checks.

The code is compiled under XCode 3.0, with the MacOSX10.4u.sdk base SDK path, but the deployment target set to Mac OS X 10.3.
