            Bug ID: 18001
           Summary: Using backtrace(), caller(), or callers(n) causes a
                    gcc internal error
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: translator
          Assignee: systemtap at sourceware dot org
          Reporter: curzonj at gmail dot com

Overview: Calling caller() causes a gcc internal error.
Reproduce:

stap -k -v -e 'probe kernel.function("dev_hold") { printf("%s", caller()) }'

Actual Results: GCC internal error during compile.
Expected Results: Compile happens and script runs

I want to use caller, but I tried callers(n) and backtrack() and they caused
the same GCC internal error result.

The compile log and artifacts are here:
