            Bug ID: 22699
           Summary: Malloc unwinder for fatal crashes fails on ARM
           Product: compiler-rt
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: compiler-rt
          Assignee: unassignedbugs at nondot.org
          Reporter: renato.golin at linaro.org

Commit 230256 has introduced a regression, where the use of
GET_STACK_TRACE_MALLOC on the fatal crash handler makes the program to abort on
ARM.

It seems ok on AArch64, which implies it's some 32 vs 64 bit issue. Maybe
testing on x86 would reveal the problem without the need to use ARM boards.
