Open perdrix52 opened 3 years ago
I replaced the x64 debughlp.dll that was in C:\Program Files (x86)\Visual Leak Detector\bin\Win64 with a more recent version which I copied from C:\Program Files (x86)\Windows Kits\10\Debuggers\x64 on my system:
and the exceptions no longer occur.
This also occurred to me just now after I enabled /DEBUG:FULL
to get symbols to display correctly, however the fix you mentioned above worked.
Is it worth dropping a new release?
I tried copying the most recent dbghelp.dll into the VLD install directory and while it prevents the crashes reported it is not able to extract the function names from the PDB files, so the call stacks only contain the module name and the address. This was a slightly newer dll than perdrix52 used: 10.0.19041.867 which I found in c:\Windows\system32.
I then tried exactly the 10.0.18362.1 version but then I don't get any call stacks at all.
This was using VS 2019 ver 16.8.4
The same setup worked fine with older compilers + older VLD versions. Unfortunately I don't know when it stopped working.
Anyone else having these problems with newer compiler versions?
I am getting lots of access violations as my application exits which appear to be related to VLD.
