Comment #1 by timothee.cour2 — 2016-10-01T01:24:37Z
more details: this happened with: ``` dmd -c -o- -deps -g -vcolumns -color=on -wi $lots_of_files ``` Hard to reduce because there are lots of files. After removing `-wi`, the command completes fast.

I'm sorry but we cannot fix this without a reproducible test case.
