Bug ID: 439491
Summary: SyntaxHighlighter::SyntaxHighlighter(QObject*) should
NOT use a default nullptr
Product: frameworks-syntax-highlighting
Version: unspecified
Platform: Compiled Sources
OS: All
Status: REPORTED
Severity: crash
Priority: NOR
Component: framework
Assignee: kwrite-bugs-n...@kde.org
Reporter: rjvber...@gmail.com
Target Milestone: ---
SUMMARY
SyntaxHighlighter::SyntaxHighlighter(QObject*) hands off its argument to
QSyntaxHighlighter; this function does NOT check if the parent it receives that
way is a valid pointer. Code should thus be obliged to pass a parent pointer
explicitly - QSyntaxHighlighter does this too (no default value).
STEPS TO REPRODUCE
1. Create a KSyntaxHighlighting instance by, for instance,
`KSyntaxHighlighting::SyntaxHighlighter syntaxHighlighter;`
OBSERVED RESULT
A crash will result in QSyntaxHighlighter::QSyntaxHighligher().
EXPECTED RESULT
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma:
