Comment 1 Vladimir Kvashin 2014-10-29 08:21:38 UTC 
I guess it's just incorrect error processing in cnd.discovery/src/org/netbeans/modules/cnd/discovery/buildsupport/CompileSupport.java:156

It does not make sense to report IOExceptions via Exceptions.printStackTrace()
If we want do display exception in a user-friendly manner, we should use
Exceptions.attachLocalizedMessage
