I've had that part get killed because of memory problems but haven't seen it segfault. It doesn't have any clues in the core dump?
yeah it's not OOM; core is pretty useless to all but the devs

i could try rebuilding with debug symbols but, sheesh
If that's the
user_proj_wrapper' then I think
Net VGND has wires outside die area` are normal for the time being. The power rings are technically placed outside ...
i'm not even up to
yet. this is just a tile for our design
@drr do you run the toolchain natively, to make debug binaries easier to manage, or do you also merge them into the docker container?
@aryap I always run it from the docker and
make merge
whenever I see new commits. The commit I have seems stable but it's not the newest
i think i can rebuild the image with debug versions of the tools by changing the docker recipes, i'll see if this evinces any clues
great news. i have a debug version of openroad.

yep. still broken
