Bug ID: 376523
Summary: Assertion failure when discarding changes in Custom
BuildSystem settings.
Product: kdevelop
Version: 5.1.0
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: BuildSystem: Custom BuildSystems
Assignee: kdevelop-bugs-n...@kde.org
Reporter: m...@flherne.uk
Target Milestone: ---
Using recent 5.1 branches, compiled from source on Arch Linux:
- Create a Custom BuildSystem project.
- Go to Project -> Open Configuration -> Custom BuildSystem
- Make some config change, but don't apply it.
- Switch to another config page.
- A dialog will appear asking whether to Apply or Discard changes.
- Select 'Discard'.
KDevelop will crash with the following backtrace. This doesn't occur if
selecting 'Apply', or with other build plugins (at least Make, CMake).
---------
ASSERT: "ui->currentConfig->count() == configs.count()" in file
