[Qbs] Crash after build

[Maximilian Hrabowski]

Hi,
i also encounter a crash with qbs 2.3 during project resolving that is difficult to grasp — i should check it with a debug build.

It happens when the project was resolved by a previous run and then something has changed.

I can work around the crash by settings —jobs 1 (or —jobs 4) or some other small value.
—jobs 1 always avoids the crash, but most of the time —jobs 2/3/4 also does when it crashes reliably when using more.

One the resolve has finished i can stop and start over with all cores. So there seems to be some kind of race condition in the resolver?!

So does it help you to
- run resolve first with —jobs 1
- and the build
?
Cheers,
Maxim

Hi,

I am still using Qbs 1.24, because starting with version 2.0 (or so) qbs crashes after build.
We have a quite large project with lots of applications and libraries, which takes a while to load and build.

Anyhow, version 1.24 and earlier work fine, but version 2.x complete with a „qbs has crashed“ message in QtCreator.
This leads to a complete rebuild every time.

I do recall that there was an environment variable or so to enable debug logging, but I cannot find any hint to that.

So my question is, what is the best way to debug a crash of qbs?

Kind regards,
Marc Hüskens
