Format of splint output is:
[<file>:<line> (in <context>)]

<file>:<line>,<column>: extra location information, if appropriate
Typical output looks like this
test.c: (in function main)
test.c:6:11: Fresh storage f not released before return
A memory leak has been detected. Storage allocated locally is
not released before the last reference to it is lost. (Use
-mustfreefresh to inhibit warning)
test.c:5:23: Fresh storage f created
test.c:5:8: Variable f declared but not used
A variable is declared but never used. Use /*@unused@*/ in front
of declaration to suppress message. (Use -varuse to inhibit
warning)
