            Bug ID: 27163
           Summary: clang-cl: The unwind destination does not have an
                    exception handling instruction!, again
           Product: clang
           Version: trunk
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs@nondot.org
          Reporter: stephan.bergmann.secondary@googlemail.com
                CC: david.majnemer@gmail.com, dgregor@apple.com,

    Classification: Unclassified

Created attachment 16140

reproducer, gzip'ed

Another one similar to bug 27056 (but with the fix for it in): At least with
recent trunk r264998, running

  clang-cl --target=x86_64-pc-windows-mscv -Xclang -std=gnu++14 -EHa -O2 -c
test.cc

on the attached (non-reduced) test.cc(.gz) fails with

> The unwind destination does not have an exception handling instruction!
> invoke void %.pre(i8* %4, i8* %.pre55)
> to label %try.cont unwind label %catch.dispatch
> CatchSwitchInst not the first non-PHI instruction in the block.
> %6 = catchswitch within none [label %invoke.cont8] unwind label %ehcleanup
> fatal error: error in backend: Broken function found, compilation aborted!
