I can reproduce the crash. A slightly simpler test is test=:monad define for_i. <0 do. i end. )
It seems only crash for boxed value, the following did not crash test=:monad define for_i. 0 do. i end. ) IIRC there was change in loop index in j901. The crash only occurs if i is taken as the result. This didn't crash test=:monad define for_i. <0 do. i 123 end. ) or test=:monad define for_i. <0 do. i end. 123 ) On Mon, Apr 20, 2020 at 5:16 PM Dimitri Georganas <d...@biodys.com> wrote: > Apologies, another error...when trying different versions and programs > (jqt, jconsole, j-mode), I mixed up things. > > The segmentation fault happens in all cases with, > > test=: monad define > for_i.
