Hi,
This is with reference to the xmlGetGlobalState function. If this function
returns NULL due to a failure in xmlNewGlobalState function, then it will
lead to a crash in functions like __xmlBufferAllocScheme on the line
return (&xmlGetGlobalState()->xmlBufferAllocScheme);
There are a number of functions like this in globals.c and all of them
will have the same problem.
At first i thought having a check for the return value of
xmlGetGlobalState function would take care of the problem, but it will not,
because if we return NULL from there the macros defined in globals.h would
try to de-reference NULL pointers.
So I am thinking we need to return a function pointer to a dummy
function(in case xmlGetGlobalState fails) which will always return NULL in
order to solve the problem. Is this the correct way to go about it, or is
there a better way?
Thanks
Ashwin
