Hi Robotarmy,

Thank you for your report. I assume you just load all the gerber files in one go. Please answer the following questions:

1. Can you determine if it is just one particular gerber file that is problematic?
2. Does the crash happen immediately after load? That is you have no chance to zoom or pan on the loaded data.

For reference I tried to load on linux with:

And I observed no crash.

OK.

If I select multiple and open everything except for the .drl files and b.cu.gbl, it doesn't crash when I sort X2.

If I select multiple and open everything except for the .drl files, it crashes when I sort X2

If I select multiple and open everything except for the .drl files and b.cu.gbl, then load b.cu.gbl separately, it doesn't crash when I sort X2.

??!

Is this bug still reproducible on recent nightlies? I just tried and could not reproduce even using the steps in #5.

[jean-pierre charras (jp-charras)]

I am unable to reproduce this issue (tested on W7 and Linux/Kubuntu)
So, because it is a old bug, I am thinking some change has fixed it.

I flag it as fixed.
Please feel free to reopen it if it happens.
