           Summary: WebAssembly: several tests added in r214504 crash when
                    building with GCC

          Severity: Normal
          Priority: P2

The pattern foo->bar([f = WTFMove(foo)]); crashes when building with GCC, I assume the move happens before the foo is used to invoke the function.
