            Bug ID: 39355
           Summary: [ASAN] detect_stack_use_after_return can hide "index
                    {} out of bounds for type" error
           Product: compiler-rt
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: asan
          Assignee: unassignedbugs at nondot.org
          Reporter: lebedev.ri at gmail.com
                CC: llvm-bugs at lists.llvm.org

Very sadly  don't have a standalone reproducer,
but if detect_stack_use_after_return=1, then there is no asan report
(and sanitizer-less build crashes),
while if detect_stack_use_after_return=0, then there is an asan report.

I can provide full code with the problem if anyone is interested though.
