help on memory allocation(?)

Hi everyone:
I'm debuggering a package and have a problem, simply speaking, this package produces 2-D grids for image pixels and do some calculations, when I use 16*16 grids, everything is ok, but when I use 32*32 grids, in the output file some places have "*******"instead of numbers, when I use 64*64 grids, more "*******" found in output file.



I think it is a kind of memory allocation problem, but I'm not sure, the trick is, if it is memory allocation problem, why the output file can produce some right numbers (for example, 32*32 grids, some numbers are correctly produced, even some numbers are incorrectly produced with "*******")? especially the correct numbers and incorrect "******" produced by same way...

thank you

There are several things can could be wrong. It may have nothing to do with memory allocation at all.

We can't really help you without seeing code though.

Could it be formating problem? when number is bigger than the width modifier of printf?

you r absolutely right, I have figured out the problem by give numbers more space to display^_^, a small bug for that package, thank everybody here!
