Hi,

This will be fixed by using the alternative bytecode set, likely in the next few weeks in Pharo 6 alpha/beta. Basically control flow messages (ifTrue:, to:do:, etc.) cannot have too many statements in their blocks (ifTrue: argument, to:do: second arguments, etc) or the compiler can't compile them due to bytecode set encoding limitation. The new bytecode set is encoded differently and allows such code to be compiled.

As a temporary solution, you need to split your code in multiple methods to lower the number of statements inside blocks inside control flow messages. 

Sorry for the annoyance. We're working on integrating a solution and we believe that this will be integrated in Pharo 6 in the next few weeks.

Regards,

Clement

Hi,

Sometimes (and also today) after formatting and saving a method, an Error is
thrown.
Following a chunk of PharoDebug.log
