Bug ID: 115461
Summary: lsan doesn't work on s390x
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: sanitizer
Assignee: unassigned at gcc dot gnu.org
Reporter: mpolacek at gcc dot gnu.org
CC: dodji at gcc dot gnu.org, dvyukov at gcc dot gnu.org,
jakub at gcc dot gnu.org, kcc at gcc dot gnu.org
Target Milestone: ---
It appears that -fsanitize=leak has no effect on s390x; it doesn't detect even
the simplest leaks:
```
#include <stdlib.h>
#include <stdio.h>
int main() {
void* ptr = malloc(123);
printf("%x\n", ptr);
return 0;
}
```
On x86_64, I get:
=================================================================
==69068==ERROR: LeakSanitizer: detected memory leaks
Direct leak of 123 byte(s) in 1 object(s) allocated from:

SUMMARY: LeakSanitizer: 123 byte(s) leaked in 1 allocation(s).
Incidentally, we have *no* -fsanitize=leak tests whatsoever.
