Bug ID: 37033
Summary: [m32][debug] FE fails with "LHS is a reference type?"
assertion on "va_end" builtins redeclaration
Product: new-bugs
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: new bugs
Assignee: unassignedbugs at nondot.org
Reporter: ilia.taraban at intel.com
CC: llvm-bugs at lists.llvm.org
FE crashed with assertion using m32 and debug build instead of "diagnostic
error" (like on m64).

void __builtin_va_end(void *);
