I finally found a fix for the crash I was experiencing. I went back and read
the documentation for libxml2 and found this (
http://xmlsoft.org/threads.html)
"call xmlInitParser() in the "main" thread before using any of the libxml2
> API (except possibly selecting a different memory allocator)"
>
After making the following change to xml.cpp, everything works fine.
if(_reader)
return true; //do not need to make a new reader
//fix crash on GC in the C# bindings
xmlInitParser();
//If the inputstream is not at the start (probably arising in
fastsearch),
//save its position and rewind so that the reader initialization is ok.
//(Getting the requested object is handled in ReadXML(), when the format
is known.)
_requestedpos = GetInStream()->tellg();
The root cause of the crash was that the CLI runs finalizers in a separate
thread, but libxml wasn't being setup for a multithreaded environment. While
I don't think that adding this call will impact the base code, I wanted to
run it by more experienced C++ programmers before committing anything.
