FINAL RESULTS:
data/fst-0.115.1/src/FstHost/FstHost.cpp:528:3: [4] (format) snprintf:
If format strings can be influenced by an attacker, they can be exploited,
and note that sprintf variations do not always \0-terminate (CWE-134). Use
a constant for the format specification.
snprintf(effectname, 1024, filename);
