Ok, should be fixed now.

Correct! And whenever I get a warning I need to run LyX from scratch
again in order to ensure that one report is not caused by a former one.
(I.e. the reports you get are the initial ones).

I think this one comes from the constructor of MathStackXIter:

MathStackXIter(int n = MAX_STACK_ITEMS): imax(n) {
item = new MathedXIter[imax];
i = 0;
}

If I am not mistaken, the contructor of MathedXIter is not called
here. What is the best way to make it happen? I know the proper way is
to use a vector, but an even better way would be to dump the struct
altogether and use an existing STL template.

I am looking now for an easy fix. The theory is that, the more purify
warning we shut off, the easier it gets to see the others.

[Michael Schmitt]

Hi,

below please find some reports concerning 'math' operations. This will
be the last report for today (sigh?). I hope you will be able to fix at
least some of the 'bugs'. It should be fairly easy to fix Uninitialized
Memory Reads (UMRs). If you think that some of them are corrected, I
will continue testing.

Michael

PS: Bug report #4 must be fixed definitively. I got a long sequence of
complaints after the one I sent you.
