Bug ID: 387249
Summary: KDevelop Language support C/C++ compilers UI crashes
when clicked on manually added compiler.
Product: kdevelop
Version: 5.2.0
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: UI: general
Assignee: kdevelop-bugs-n...@kde.org
Reporter: vbs...@centrum.cz
Target Milestone: ---
KDevelop Language support C/C++ compilers UI crashes when clicked on manually
added compiler.
* How to reproduce? *
1. Start KDevelop, manually add Clang compiler (Settings=>Language
support=>C/C++ compilers)
2. Close KDevelop
3. Start KDevelop
4. Open "Settings=>Language support=>C/C++ compilers"
5. Click on previously added compiler.
* What happens? *
- KDevelop crashes.
* Expected behavior? *
KDevelop should allow to edit the compiler record.
* Observations / Notes*
- KDevelop crashes on the line
"kdevelop/plugins/custom-definesandincludes/compilerprovider/widget/compilerswidget.cpp:177".
It looks it crashes on calling "indexes.first()" event there is an assert two
lines above guarding the "indexes" not to be empty.
- Backtrace shows following locals:
```code
(gdb) info local
indexes = {<QListSpecialMethods<QModelIndex>> = {<No data fields>}, {p =
{static shared_null = {ref = {atomic = {_q_value = {<std::__atomic_base<int>> =
{static _S_alignment = 4, _M_i = -1}, <No data fields>}}}, alloc = 0, begin =
0, end = 0, array = {0x0}}, d = 0x152eb80}, d = 0x152eb80}}
compiler = <optimized out>
```
- It happens at least in KDevelop 5.1.x to 5.2.x including my home build made
from recent git sources.
- Also please see attached video for how to reproduce and some GDB output.
- Anyway it is not clear what is this Compilers for. ?
- Also do not understand why it always selects GCC as autodetected when my
system uses Clang as default. ?
