Bug ID: 409939
Summary: App crash when writing c++17 style "for loop"
iterating over elements of a std::unordered_map using
structured binding declaration
Product: kdevelop
Version: 5.3.3
Platform: Appimage
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: Code completion
Assignee: kdevelop-bugs-n...@kde.org

Desktop capture of the bug
SUMMARY
Observed in 5.3.3 and 5.3.2
When writing code for iterating over an unordered_map using the following
syntax :
for(const auto& [key,val] : map)
{}
the software crashes (not always) usually when typing the "] : map" section of
the line
STEPS TO REPRODUCE
1. Interactively try to write something like "for(const auto& [key,val] : map)"
in a file ; in my case it was in a header file part of a c++ project with the
parser set to std=c++1z.
An attached video illustrates the problem.
OBSERVED RESULT
App may crash, on reload the file is usually properly recovered ; seems to come
from the code completion feature, but not 100 sure.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Linux (x86_64) release 4.15.0-54-generic
KDE Frameworks Version: KDE Frameworks 5.54.0
