" Note: when using the new array bounds checking flags:  Each warning
" usually has several lines and several references to source code mostly
" within one or two lines (see sample warning below).  The easiest way
" not to mess up file name detection and not to jump to all positions is
" to add something like
"	-linelen 500 +boundscompacterrormessages
" to your .splintrc and 'set cmdheight=4' or more.
" TODO: reliable way to distinguish file names and constraints.
"
" sample warning (generic):
"
"foo.c:1006:12: Clauses exit with var referencing local storage in one
"		       case, fresh storage in other case
"   foo.c:1003:2: Fresh storage var allocated
"
" sample warning (bounds checking):
"
"bounds.c: (in function updateEnv)
"bounds.c:10:5: Possible out-of-bounds store:
"    strcpy(str, tmp)
"    Unable to resolve constraint:
"    requires maxSet(str @ bounds.c:10:13) >= maxRead(getenv("MYENV") @
"    bounds.c:6:9)
"     needed to satisfy precondition:
"    requires maxSet(str @ bounds.c:10:13) >= maxRead(tmp @ bounds.c:10:18)
"     derived from strcpy precondition: requires maxSet(<parameter 1>) >=
"    maxRead(<parameter 2>)
"  A memory write may write to an address beyond the allocated buffer. (Use
"  -boundswrite to inhibit warning)
