Right Click Cell Backtrace #766

Closed yrrapt closed 3 years ago

yrrapt commented 3 years ago

When I right click on a cell on the cell list on the left I receive a back trace dialog with the information below.

This happens regularly but not always.

Let me know if there is any more information you'd like me to provide to to assist in tracking down the cause.

klayoutmatthias commented 3 years ago

@yrrapt Thanks for this backtrace. It's already helpful, but debugging that is going to be some pain ...

klayoutmatthias commented 3 years ago

@yrrapt The back trace is already good, but I could not really reproduce the problem. Do you have any hints for me? Like maybe explaining what you did before that? Have you been editing? Using PCells?

Thanks,

Matthias

yrrapt commented 3 years ago

@klayoutmatthias Apologies for the delay I wanted to replicate the issue exactly and didn't get a chance until today. The exact where this just happened to me is this:

I was editing the dac_bias of the attached gds (saved immediately after the error popped up). I tried to right click on dac_unit_cell and the following back trace popped up:

Then I click ok on the traceback then a dialog pops up saying 'Operation Cancelled'.

I hope that was useful. amsat_txrx_ic.gds.zip

klayoutmatthias commented 3 years ago

@yrrapt No need to apologize - thanks for this testcase!

I'm afraid I still can't reproduce it, although I ran a some experiments with valgrind which is usually a very reliable way to detect memory corruption issues.

I noticed the test case contains references to the sky130 library. Maybe the issue is related to them. Do you have a pointer where I can get these?

One more question: are you using a build which is based on a recent code base? Would you mind pasting the text you see in "Help/About" here?

Thanks,

Matthias

klayoutmatthias commented 3 years ago

@yrrapt I have some reason to hope that issue-795 relates to this issue. I'd ask you to test your case again when this bug fix is merged into the master or release as 0.27.1.

Thank,

Matthias

yrrapt commented 3 years ago

@klayoutmatthias Great, I will try it once I've installed 0.27.1

klayoutmatthias commented 3 years ago

@yrrapt Any updates? Do you still see this issue?

Thanks,

Matthias

klayoutmatthias commented 3 years ago

I guess this issue is solved.
