Re: [xml] libxml2 crash

["Floodeenjr, Thomas" <thomas_floodeenjr mentor com>]

The crash goes away if I switch from zlib-1.2.5 back to zlib-1.2.3.

 

Is zlib-1.2.3 sufficient for libxml2-2.7.8?

 

Thanks,

-Tom

I confirmed that get this crash running the ./libs/testapi test, and not just in my application.

 

libxml2-2.7.8 Red Hat 4u6 with gcc 4.1.2.
