I'm am writing a window manager which uses XpmCreateImageFromData(3)
to read a .xpm file containing the theme of the decoration of the
windows. The program segfaults when calling this function. I use this
function rather than XpmCreatePixmapFromData(3) in order for me to get
a pixel color from the .xpm with XGetPixel(3).
This is the code of the window manager:

This is the .xpm I am reading:
https://github.com/phillbush/shod/blob/master/theme.xpm
This is what I get running the program under gdb.
