[Nano-devel] syntax coloring segfault

[Wouter Van Hemel]

Hello,

I get a segfault with nano 1.2.0 syntax coloring on Linux. My nanorc
is the one included as a sample with the source tarball (uncommented
syntax coloring). The file being edited is nano.c (in the 1.2.0 tarball).

  # ./nano nano.c
  [ builds screen ]
  Segmentation fault

More info below.

I like how small nano still is, even after adding all these new features.
Keep it tiny. ;)


Regards,

  wouter
