win7 x64 memory errors

[bryan314]

Hi all,

 

I recently moved over X2 to win7 x64. Chooks that had no issues on XP 32 are now crashing. So far all crashes seem to be related to memory issues. Some I've been able to fix. Others have me stumped.

 

For example: calling stdc free() (per the documentation) on the data from ps_tag_to_mc_ents(). 2 out 3 chooks this is used, it works fine. The 3rd (and simplest chook) crashes.

 

The code for the 3 routines is:

Call ps_tag_to_mc_ents with an edge tag

loop resulting ent(s)

if ent meets a criteria, delete it.

free eptrs array

 

debug is breaking on the free() or more specifically _ASSERTE(_CrtIsValidHeapPointer(pUserData)); in dbgheap.c

 

Is there a compiler setting I should be looking for?

 

Is the stdc free() the wrong function? Several mc api functions provide their own free routine. is the free for ps_tag_to_mc_ents missing from the api?

 

In the api FREE() seems to be a wrapper for stdc free(). Should I be using m_free() in mastercam? Or something else?

 

 

Any thought would be appreciated.

Fresh install of vc++. I'm wondering if the chook is being compiled against a different version of the crt and the malloc/free version mismatch is causing this. Have to wait until monday to test.

removing kb971090 (8.0.50727.4053) seemed to fix this.
