segfault on ubuntu 10.10

Capt:

• Using coffeescript version 1.0.1
  EDIT: node v0.4.7

[bnolan]

Are you getting a stacktrace - or just a segfault? Are you in the project directory when running capt? I'm using node v0.4.1, I'll try upgrade to 0.4.7 and see if I can repro.

[danielzzz]

just a segfault. I tried with v0.4.1 but I am also getting a segfault. maybe it's something related to my system config, but no idea how to trace it :(

Same here. I managed to get a core dump and a stack trace (presumably the core comes from node exec):

fred@aleph:~/dev/sarin3$ capt server

Note also that the same is happening when running 'capt watch'

I ran few tests on Ubuntu and tried to track the problem down. I suspect there may be an issue with a glob:
for path in Glob(Path.join(@cwd, pathspec))

the segfault happens for cases when path doesn't contain actual files for example:
Glob(Path.join(@cwd, 'public/stylesheets/*.css'))
Glob(Path.join(@cwd, 'public/stylesheets/*.less'))
