Bug ID: 16705
Summary: Crash with pragma after a case or a default
Product: clang
Version: 3.3
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
Crash is there is a pragma right after a case: or a default:
void __td_ta_lookup_th_unique()
{
int t = 0;
switch (t)
{
case 1:
#pragma weak t
;
}
}
There is an assert in CodeGenFunction::EmitStmt assert(S && "Null statement?")
There is a null statement there because in Parser::ParseCaseStatement,
ParseStatement() return a null statement. (same problem in
ParseDefaultStatement)
(Bug seen in nptl_db/td_ta_map_lwp2thr.c from glibc)
