today it's `or_route.tcl` that hates me. has anyone run into this?
```[WARNING] Net VPWR has wires outside die area
[... multiple... ]
[WARNING] Net VGND has wires outside die area
[... multiple... ]
[W[ERROR]: during executing: "openroad -exit /openLANE_flow/scripts/openroad/or_route.tcl |&amp; tee &gt;&amp;@stdout /openLANE_flow/designs/250/asic_config/clb_tile/runs/debug/logs/routing/fastroute.log"
[ERROR]: Exit code: 1
[ERROR]: Last 10 lines:
child killed: segmentation violation```

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

```#0  0x0000000000a0addc in std::_Rb_tree&lt;int, std::pair&lt;int const, std::vector&lt;odb::Rect, std::allocator&lt;odb::Rect&gt; &gt; &gt;, std::_Select1st&lt;std::pair&lt;int const, std::vector&lt;odb::Rect, std::allocator&lt;odb::Rect&gt; &gt; &gt; &gt;, std::less&lt;int&gt;, std::allocator&lt;std::pair&lt;int const, std::vector&lt;odb::Rect, std::allocator&lt;odb::Rect&gt; &gt; &gt; &gt; &gt;::_M_erase(std::_Rb_tree_node&lt;std::pair&lt;int const, std::vector&lt;odb::Rect, std::allocator&lt;odb::Rect&gt; &gt; &gt; &gt;*)

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 `user_proj_wrapper` yet. this is just a tile for our design

<@U01E2KKE4SH> do you run the toolchain natively, to make debug binaries easier to manage, or do you also merge them into the docker container?

<@U01837QU37V> 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.

then `sudo make build-openroad_app`  and `sudo make merge`

bad news. i still have this problem.
