Hello,

The faulty code bellow when debugged and 'step through' cause the
debugger to hang:

self inform: '1'.
#(2 3 4) select: [:i| i] thenDo: [:n| self inform: n printString ].
self inform: '5'.

It seems trapped in an infinite loop, you can more or less get control
back with Alt+[.]


When step in, the debugger properly report the error.

Pharo #60362.


I did not see similar bug report, shall I?
