Bug ID: 38361
Summary: ICE Getting frame offset for a dead object
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: -New Bugs
Assignee: unassignedclangbugs at nondot.org
Reporter: zhonghao at pku.org.cn
CC: llvm-bugs at lists.llvm.org
The code is as follow:
#include <alloca.h>
#include <stdint.h>
int
main(void)
{
volatile char *a;
unsigned int i;
a = alloca(SIZE_MAX);
for (i = 0; i < 1; i++)
a[i] = 1;
return 0;
}
The error messages are as follows:
clang-7: /usr/local/lib/llvm7.0/include/llvm/CodeGen/MachineFrameInfo.h:470:
int64_t llvm::MachineFrameInfo::getObjectOffset(int) const: Assertion
`!isDeadObjectIndex(ObjectIdx) && "Getting frame offset for a dead object?"'
failed.
