strange excel crach with macro repetition

[Mau]

I have a macro written in vba that process some data from a worksheet and
put them into chart objects in the same chart.

When the same macro, on the same data, is repetated, after several
execution, excel crashes and I have to kill the process. Sometimes the crash
made also the xls file unreadable and corrupted.

The error that VBA tells me is something like "impossible to set the XValues
property of the series object" (I Have excel in italian)

It seems like if something in Excels grows at each execution of the macro,
until it reaches an overflow, and it crashes.
Other people around internet have the same problem, but no one fixed

Can you please help me?

I'd suggest trying microsoft.public.excel.programming, you may find specific
help there. When you post, please post the relevant pieces of your code so
others can see what your code is doing, and thereby give better feedback.
Best,
