Hi Andrei, would you mind opening an issue for this, making a comment in a merged PR does not help to see it.

Thanks��

Hi,

Executed in the latest Pharo 7 image (Pharo-7.0.0+alpha.build.1310.sha.a454977bb3d55bc4fcca3a57ac2fafcf137c0f30 (64 Bit)) the code below blocks the image (both with latest and stable vm on MacOs HighSierra). The vm does not crash but gets into a "Not Responding" state and does not get out:

Class new ��������������

���� ����superclass: GLMTransmission; ��������������

���� ����setFormat: GLMTransmission format;

�� �� ��classLayout: GLMTransmission classLayout copy; ��������������

�� �� ��yourself��

Code like this is used in Moose in some tests and in SmaCC in the rewrite engine:

Class new��������

���� ��superclass: SmaCCRewriteMatchContext; ������

�� �� setFormat: SmaCCRewriteMatchContext format; ��������

�� �� classLayout: SmaCCRewriteMatchContext classLayout copy; ������

�� �� yourself.��

This worked in Pharo 6. Bug or here should be a different way to do this?

Cheers,

Andrei
