@aceofspades: Thank you very much for helping us integrate coverity into travis!
Send uninteresting output to /dev/null
test
Coverity/Travis integration works

@aceofspades Thank you again! ;)
Another try
Try clang instead of gcc for coverity
Try using new token
Use gcc again
Might be a work around
trial and error
Using bash instead of sh may fixes [[ not found error
Merge branch 'dev'
