> Run the unit test {{TestConvertFunctions}}. The {{testBinaryString}} test emits an ASM error (see below), though the test succeeds. In addition, the test {{testConvertFromConvertToInt}} also emits the error if the line to turn off scalar replacement is commented out (see test.)
> Another bug complains about the stack trace displayed when scalar replacement fails.
> This bug says that we should either not use scalar replacement if we can predict it will fail, or disable scalar replacement altogether so that we get clean tests. (Work elsewhere suggested that the Java compiler and runtime already to scalar replacement for us in the latest Java versions.)
> Stack trace:
