Thanks for the report. Fixed here:

[xml] Potential NULL pointer dereference in xmlregexp.c

[Shaobo He via xml]

Hello everyone,

I'm Shaobo He, a graduate student at University of Utah. I'm running a
static analysis tool on libxml2 and noticed there may be a NULL pointer
dereference in function `xmlRegexpIsDeterminist`. Basically, function
`xmlNewAutomata` can return a NULL pointer when malloc fails. Please let me
know if it makes sense or not.

Thanks,
Shaobo
