Summary: checking for malloc failures

Initial Comment:
expat 1.95.2 (under RedHat linux 2.4)

The following code (xmlparse.c:578) will crash, should
the malloc() call fail:

    XML_Memory_Handling_Suite *mtemp;
    parser = malloc(sizeof(Parser));
    mtemp = &(((Parser *) parser)->m_mem);
    mtemp->malloc_fcn = malloc;


Likewise (xmlparse.c:1139) XML_GetBuffer() returns NULL
when malloc() fails, and the result is not checked:

    memcpy(XML_GetBuffer(parser, len), s, len);

Other than that, expat works quite well.  Very nice
library.

-Eric
