Hi, my custom frontend for VirtualBox seemed to work fine and stable but then I started to play around with number of CPU's and memory and I started getting "An invalid or unaligned stack was encountered during an unwind operation" from VBoxREM.dll. I downloaded the sources for VirtualBox 4.3.18, built it for x64 debug and started debugging.
* The first weird thing was that I could not find a .pdb file for VBoxREM.dll, is that some kind of special .dll? I have pdb files for VBoxC.dll and friends under "out\win.amd64\debug\stage\debug\bin" but I can't find one for VBoxREM.dll. * The stack trace is (I know it won't give much help): ntdll.dll!00007ffe679ac0b4() Unknown ntdll.dll!00007ffe67913356() Unknown msvcrt.dll!__longjmp_internal () Unknown > VBoxREM.dll!000000006fb0f3c4() Unknown The frontend does not have any output from VirtualBox on stdout or stderr and the logfile also does not show any errors. Could anyone provide any pointers how should I approach debugging this? Best Regards, Rudolfs Bundulis
