Bug #: 13131
Summary: warn on NULL as vararg argument
Product: clang
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Frontend
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
Consider:
execl("/bin/true", "true", NULL);
We do not warn on this, but the code is broken if NULL is defined as 0. We
should warn whenever NULL is passed through a vararg (and expands to an
integer).
