QuickTime SDK for Windows ICMCompressionSessionEncodeFrame crashes for higher resolution cameras 2 MP

Question

I implemented a while ago a H.264 re-encoding to output H.264 QuickTime .mov file usng QuickTime Window SDK  7.3.0.70. The code uses ICMCompressionSession to compress the frames going into the container. The code works fine with cameras with resolutions up to 2 Megapixels (1600 x 1200). The crash occurs in QuickTime API call. Here is the code to compress the frame:
CVPixelBufferRef pixel_buffer = nil;
int nWidth = (**pixMap).bounds.right - (**pixMap).bounds.left;
int nHeight = (**pixMap).bounds.bottom - (**pixMap).bounds.top;
CVReturn ret =
CVPixelBufferCreateWithBytes(kCFAllocatorDefault,
                             nWidth,
                             nHeight,
                             k24RGBPixelFormat,
                             GetPixBaseAddr(pixMap),
                             3 * nWidth,
                             NULL,
                             NULL,
                             NULL,
                             &pixel_buffer);
//.....code ommitted for clarity
// set image data into the pixel buffer
CVPixelBufferLockBaseAddress( pixel_buffer, 0 );
// Feed the frame to the compression session.
m_OSerr = ICMCompressionSessionEncodeFrame( compressionSession, pixel_buffer,
        displayTimeMsecs, displayDurationMsecs, validTimeFlags,
        frameOptions, NULL, NULL );
//unlock the pixels
CVPixelBufferUnlockBaseAddress( pixel_buffer, 0 );
CVPixelBufferRelease(pixel_buffer);
The call to ICMCompressionSessionEncodeFrame fails either  with
1. Error code -108
memFullErr = -108, /*Not enough room in heap zone*/
OR
2. An access violation QuickTimeH264.qtx!6782522d()

Has anyone encountered the same problem and if so what was the resolution?
