"[lldb-mi] Fix hanging of target-select-so-path.test".
apolyakov edited the summary of this revision.
apolyakov added a comment.
I found out that the reason of hanging of the test suite was in incorrect usage
of Filecheck and lldb-mi processes in target-select-so-path.test. Current patch
has been tested on CentOS 7.
