           Summary: Stack backtraces in exceptions not supported
           Product: new-bugs
           Version: unspecified
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: new bugs

The Ada -E binder option stores a stack traceback in the exception.
This doesn't work with llvm-gcc.  Testcase:

procedure Trace is
   raise Program_Error;

$ gnatmake trace.adb -bargs -E
gcc -c trace.adb
gnatbind -aO./ -E -I- -x trace.ali
gnatlink trace.ali
$ ./trace
Segmentation fault (core dumped)
