Thanks for reply. I checked the path and it is ok. I test directly with
no variable and the result is identical.
I did some other experiments. In the batch script, I can successfully
run
bundle exec rake --version or bundle exec rake -h
However, when I run bundle exec rake -T, it would produce exact
segmentation error as follows:
crontab-test.sh: line 6: 29245 Abort trap: 6
/usr/local/Cellar/ruby/2.0.0-p195/bin/bundle exec rake -T >>
/tmp/cron-test.out
/usr/local/Cellar/ruby/2.0.0-p195/lib/ruby/gems/2.0.0/gems/mysql2-0.3.13/lib/mysql2/mysql2.bundle:
[BUG] Segmentation fault
ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin12.0]

I don't understand when bundle exec rake would encounter errors for
mysql2 bundle, especially when it reports ruby 1.8.7 while I am sure I
use 2.0.0p195.
