>             Project: Groovy
>          Issue Type: Bug
>          Components: class generator
>    Affects Versions: 2.4.14, 2.5.0
>            Reporter: John Wagenleitner

> The following will fail with 2.4.14 and above.
> {code:java}
> class Account {
>     int balance = 0
>     void credit(int add) {
>         this.@balance += add
>     }
> }
> def acct = new Account()
> acct.credit(3)
> assert acct.balance == 3
> {code}
> Fails with the following in 2.5.0
> {code:java}
> groovy.lang.GroovyRuntimeException: ASM reporting processing error for Account#credit with signature void credit(int)
> {code}
> And this starting in 2.4.14
> {code:java}
> java.lang.VerifyError: (class: Account, method: credit signature: (I)V) Unable to pop operand off an empty stack
> {code}
> Possibly related to the fixes for GROOVY-8385 and the operand stack not being marked to handle the compound assignment operators.
> Issue reported on the [dev mailing list|https://mail-archives.apache.org/mod_mbox/groovy-dev/201806.mbox/%3Cef1093fea2ceab17b52fc021631b7b2b5e86ca4e.camel%40winder.org.uk%3E].
