[jira] [Created] (GROOVY-9937) internal compiler error during
instruction selection
Thodoris Sotiropoulos created GROOVY-9937:
---------------------------------------------
Summary: internal compiler error during instruction selection
Key: GROOVY-9937
URL: https://issues.apache.org/jira/browse/GROOVY-9937
Project: Groovy
Issue Type: Bug
Components: Static compilation
Affects Versions: 3.0.7
Reporter: Thodoris Sotiropoulos
I have the following (incorrect) program
{code:java}
class Foo {
static void foo() {
return 1
}
}
{code}
The compiler crashes during the instruction selection phase producing the following output. From what I understand is that the type checker misses the error, and the compiler crashes during bytecode generation.
{code:java}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
General error during instruction selection: Cannot use return statement with an expression on a method that returns void
