Okay, can only get it to crash when first signing a document using libxmlsec, so I suppose I'll simply assume that the two libraries use the error log in incompatible ways. could you check if this patch makes it work better for you? It basically restricts XSLT error logging to the lifetime of an XSL transformation.

I still need to compile lxml with -ggdb, where do I stick that in the setup.py/makefile?
Pass the "CFLAGS" env variable when calling setup.py, as in CFLAGS="-O -ggdb" make clean inplace
still crashed with the patch for me:

Fortunately, I've been able to simplify my crash conditions somewhat, so the valgrind log is significantly shorter.
You can generally strip the "... within /lib/ld-2.6..." entries from it.
Looks like I'll need to find some time to work on that test case after all.
Please do, and also re-run your valgrind test with -ggdb. There seem to be some interesting problems in there (the "moveNodeToDocument()" sections), even if only crashes later. Seeing the line numbers here would really be helpful. Stefan
