Devil segfault, problems with png, bmp

Question

I am in mingw (gcc version 4.5.2).

I get segfault when opening certain files, including PNG and BMP. It worked fine on PNG 128x128, but when I started testing files with large files, I started getting segfault. However, there are no problems with the TGA format. I know that the library works for the most part, but not knowing if it decides to crash and burn, this is not good.

gdb does not give me any clues about what is going on. I can compile DevIL from the source, and I compiled the dll debug ( --enable-debug for configure script), but it doesn't seem to support png (I think I need to get the png12 library), but it isn’t "I'm very far.

I am trying to open a 2 MB BMP that I made in GIMP. I run it through GDB and sometimes it will be segfault, but in other cases it warns about some things happening on the heap (a lot of things that I have never seen before). This is where the gdb dump starts. All lines starting with %%% are output specific to my program, the rest are from gdb.

The ilWritePng test actually just writes the .tga image file. This test works fine with dll release (md5 = 59E291838AE2C88F5F71108E4845A84B), but in this debug build I collected more problems.

I was so happy when I shot the document and got Devil and worked like 10 minutes. I decided that it would save me , so it works a lot ...

This makes me wonder if I should just implement my own image file format (I would use a binary PPM file and drag it through the compression stream).
