The crash was indeed in libxml2, but I could not get the bug to repro in

  Just wondering, are you by chance changing the libxml2 buffer allocation
strategy in the application code (function xmlSetBufferAllocationScheme())
and associated global variable (I know I know ...) xmlBufferAllocScheme.
That may explain if you switched to an exact allocation policy why
you hit the buffer overrun while it usually doesn't show up,
