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.
