Hallo
Which version of the libpng do you use ?

I have not been able to reproduce that problem on my machine.

That lookes strange.

Would it be possible to recompile the png2yuv, and change a few lines ?
Add a few lines around:
png_destroy_read_struct(&png_ptr, &info_ptr, &end_info);
so it lookes like that:
if (setjmp(png_ptr->jmpbuf)) {
png_destroy_read_struct(&png_ptr, &info_ptr, &end_info);
return 2;
}
---ENDE---
you find theline in the png2yuv.c in line 405.
The other mail from you:

The thing about I have read is a problem with a pointer. But I didn't
find a solution.

I don't think that this will make any difference.
