About 2% of compiler commands corresponding to Linux 3.14, 3.16 fail due to incorrect implementation (I do not think that the first implementation has not such the issue):
Couldn't find string in the hash table

I observe the failure when the number of strings exceeds 97. It seems that neither a string content nor their usage context influences. So, the issue seems to be with a hash table that fails to keep a big number of strings.
