Pcbnew GAL crash: Unhandled exception class while routing

[Ben Kempke]

When routing certain nets, pcbnew crashes when in GAL mode showing the error 'Unhandled exception class: N5boost16exception_detail10clone_implINS0_19error_info_injectorISt12out_of_rangeEEEE what: Unable to find key in unordered_map.' when routing certain nets.

The attached board and screenshot can be used to reproduce this problem.

[Tomasz Wlostowski (twlostow)]

Is the crash systematic? Could you attach a stack trace?

Tom

[Ben Kempke (bpkempke)]

Yes, the crash is systematic. I've added the stack trace above.

[Nick Østergaard (nickoe)]

@Ben, can you list or screenshot your router settings? Press E while having the routing tool selected.

[Nick Østergaard (nickoe)]

Degrading importance a bit because it is not really a segfault, more like an assert.

[Nick Østergaard (nickoe)]

@Ben where did you get this build from? Is it from the PPA?

I might be nessesary to use boost 1.54 to reproduce this, and if you built this yourself and skipped the kicad boost building this could be the root cause of this. 1.54 needs some patching.

[Tomasz Wlostowski (twlostow)]

The stack trace has an assert in different function than the screenshot...

T.

[Ben Kempke (bpkempke)]

The posted issue was built by me, but the issue persists after testing with the latest PPA. The error manifests in two different ways: either the program throws a SIGABRT and immediately kills the program or shows the error message then kills the program once dismissed. This may account for the differing stack trace vs. error message. Once I have some free time, I could look into fixing this error, but I figured I would report it since this has made routing particularly difficult with this board, and I know the stable release is coming out shortly. Attached is the screenshot of the crash on the latest PPA:

[Ben Kempke (bpkempke)]

Also, my router settings.

[Nick Østergaard (nickoe)]

So far you are the only one being able to reproduce. Could you possibly try to upgrade boost to something above 1.54, maybe even 1.58?

You shall use the KICAD_SKIP_BOOST option to make it not build kicad's boost.

[Ben Kempke (bpkempke)]

Unfortunately, the issue remains with Boost 1.58. Nothing I'm doing seems atypical, and the issue has been replicated on two machines for me now. The project was configured with the normal flags plus the added KICAD_SKIP_BOOST option:

Which exact nets should we route to make the error appear? I tried to route from the pad in your screenshot and connect it to the other pad it should be connected to. I also tried some others random nets.

[Ben Kempke (bpkempke)]

The most reliable way for me is to replicate the exact trace path as shown in the original screenshot, then attempt to move the cursor directly to the right under the shown via. Make sure to _not_ commit any of the traces, and just replicate the trace path through cursor movements. The angle which the original trace comes off the shown pad appears to affect whether the crash occurs or not, so the 270 degree angle appears to be necessary in this situation.

[Ben Kempke (bpkempke)]

Of note: I am also able to recreate the problem on the latest mac nightly (5871)
