this issue does not happen with version 1.6.8

[ringabout]

The devel branch defaults to ORC, you should compare it with ORC on 1.6.8

[123swk123]

yes you are right with ORC on 1.6.8 I get the same build error

[123swk123]

as a work around I can comment out my debugs that uses repr and work on both nim versions devel &1.6.8 on 1.6.8 I'm getting runtime exception SIGSEV, but not on devel

[123swk123]

works now! Thanks for the update.
