Segmentation fault

Github doesn't support uploading BMP files. I created SOM_Chocolate from this PNG in mspaint by doing File->Save As->256 Color Bitmap

[jeffythedragonslayer]

This crash happens at the free(tilemap) call near gfx2snes.c:763

[jeffythedragonslayer]

commenting out this free allows gfx2snes to exit, but the produced .pic file appears to be corrupted.

[alekmaul]

ok, is it possible to have your source bmp file to try to debug gfx2snes ?

[jeffythedragonslayer]

Are you afraid your mspaint is different from mine? I'll send you the BMP over discord.

[alekmaul]

I'm afraid that github will not preserved the color palette :P ;)

[RetroAntho]

Or just using a zip here ? :)

[alekmaul]

no it's ok , I have the bitmap and I can reproduce the issue
