Bug ID: 443315
Summary: "Expected expression" error declaring a variable
immediately after a case label
Product: kdevelop
Version: 5.6.2
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Language Support: CPP (Clang-based)
Assignee: kdevelop-bugs-n...@kde.org
Reporter: m...@dblsaiko.net
Target Milestone: ---
SUMMARY
KDevelop analyzes a variable declaration right at the beginning of a case block
incorrectly, leading to an error while the code still compiles.
Minimal reproducible case:
// test.c
int main()
{
switch (0) {
case 0:
int i; // error: Expected expression
}
return 0;
}
After changing this code to the following, the error goes away:
// test.c
int main()
{
switch (0) {
case 0:
0; // <- inserted line, any statement will do
int i;
}
return 0;
}
STEPS TO REPRODUCE
1. Declare a variable immediately after a case label in a switch statement
OBSERVED RESULT
KDevelop will show an "Expected expression" error after the variable
declaration
EXPECTED RESULT
KDevelop parses the code correctly as a variable declaration
