<https://github.com/The-OpenROAD-Project/OpenLane/issues/1587|#1587 Segfault when Streaming out GDSII with Magic>
Issue created by <https://github.com/xobs|xobs>
*Description*

A segfault was created after several hours of running during the `Streaming out GDSII with Magic`

Note that I am using `synth.tcl` with the `autoname` patch applied. I will try again without this patch and see if that fixes things.

*Expected Behavior*

There should be no segfault. dmesg reports:

PDK Version Verification Status: MISMATCH
The version of open_pdks used in building the PDK does not match the version OpenLane was tested on (installed: 0059588eebfc704681dc2368bd1d33d96281d10f, tested: 3af133706e554a740cfe60f21e773d9eaa41838c)
This may introduce some issues. You may want to re-install the PDK by invoking `make pdk`.
