Re: Function descriptions longer than 255 cause XML parser error

Hiya,

Can you please post the stack trace?

It would seem that the exception is a buffer overflow in the type extraction
code, before the xml intermediate code is executed.

The only solution to this would be to trim that field before populating the
doc char [] or increasing the size of this and also trimming strings that
are too large.

Its likely to be a fix required in the C++ which means Roger....
