The crash was indeed in libxml2, but I could not get the bug to repro in Linux. We took the crash file and fuzzed a bit more on Linux, but no crashes were observed.
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, Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel () veillard com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/
