Invalid symlinks causes istanbul to fail

[0815fox]

I reported an issue against grunt-mocha-istanbul on this (see https://github.com/pocesar/grunt-mocha-istanbul/issues/66) but we found out, that the issue is in istanbul itself.

All works fine until I create a sym link to a file with extension '.js', which points to a not existing path. It seems not to matter, where I place that broken link.

$ ln -sT src/bar.js src/foo.js
$ ls -la src
$ grunt mocha_istanbul:server --debug

Aborted due to warnings.

I use istanbul version 0.4.5.

Even when I just run istanbul on command line:

$ node_modules/.bin/istanbul cover node

it complains about that file:

Error: ENOENT: no such file or directory, stat '/home/mk/work/4.5.1/workspace2/cloud/src/foo.js'
