Summary: reading uninitialized variable

Initial Comment:
in xmlparse.c, line 3600

    eventEndPtr = next;

my debugger complains that this is causing an attempt 
to read unitialized data.

OK, there is only one such line, but
I have it on line 3618, in xmlparse.c rev. 1.41.

Are you sure you have 1.95.3?

Anyway, the code there looks like:

...
  for (;;) {
    const char *next;
    int tok = XmlPrologTok(encoding, s, end, &next);
    eventEndPtr = next;
    switch (tok) {
...
 It looks as if XMLPrologTok initilaizes next, but
since this is dynamic behaviour (XMLPrologTok
is actually a function pointer), it cannot be
assumed for sure that it is happening.

Maybe that is what the debugger is complaining about?

Does this cause an actual error?

Like I said in the original message: line 3600 (eventEndPtr = 
next)

Cheers,
