[Vm-dev] Bulletproof BitBltSimulation against failure in #lockSurfaces

[Josh Gargus]

Hi David,

Can you please add the following patch to the VMMaker source code?  It's a one-line fix to VMMaker-dtl.156 from SourceForge.  It fixes a bug where #warpBits doesn't check the return value of #lockSurfaces, and can potentially crash when execution continues after the failed lock attempt.

Thanks,
Josh
