A static analyzer apparently reported an uninitialized use of the variable result in sem_open in the case where the file is required to exist but does not exist. The report appears to be correct; set result to SEM_FAILED in that case, and add a test for it. Note: the test passes for me even without the sem_open fix, I guess because result happens to get value SEM_FAILED (i.e. 0) when uninitialized. Tested for x86_64.
