I recently get segfaults when opening a certain file with vim in urxvt. I
failed to create a minimal case for reproducing this bug, it seems to be
related to:
- the file in question (gnu Makefile)
- my vim configuration (huge!)
- the urxvt window size (95x63)
As my vimrc uses many plugin specific settings, I didn't post it here. Let
me know if that would be of any help.
urxvt seems to crash randomly at one of the following places:
Program received signal SIGSEGV, Segmentation fault.
