LINE_NUM incrementation seems to be incompatible with bash shipped with Ubuntu 12.04.2

[ktchu]

Bug: LINE_NUM incrementation throws an "exception" when run in bash that ships with Ubuntu 12.04.2. Error was caught when using bash 'trap' mechanism to do exception handling.

Proposed solution: change ((LINE_NUM++)) to LINE_NUM=$(($LINE_NUM + 1))

Thanks for the report. Are you sure that you are using bash and not another shell? Is the test script also failing?

./test/test.sh

Hi Ruediger,

I believe that I'm using bash, but I'm not 100% sure because the error only shows up when I run the script through sudo (and there are multiple layers of scripts). I just checked that '((A++))' works from the shell prompt when I log into the machine, so I probably misreported the error as originating from bash.

I'll try to run the unit tests sometime soon and let you know if they fail.

Cheers, Kevin
