[M3devel] Juno/Win32 heap corruption

[Jay K]

I thought this was gone, but now I'm still seeing occasional heap corruption in Juno on Win32.

It has the same signature of accessing 001ffffc.

 

 

(adc.f8): Access violation - code c0000005 (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.
