Bug ID: 443342
Summary: lambda-in-connect false positive, when a lambda is
nested in another lambda
Product: clazy
Version: unspecified
Platform: Other
OS: Microsoft Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: general

lambda-in-connect-false-positive.cpp
SUMMARY
lambda-in-connect false positive when a capturing lambda is nested inside the
connected lambda.
STEPS TO REPRODUCE
1. Run clazy on attached file lambda-in-connect-false-positive.cpp
OBSERVED RESULT
lambda-in-connect-false-positive.cpp(8,4): warning: captured local variable by
reference might go out of scope before lambda is called
[-Wclazy-lambda-in-connect]
foo++;
EXPECTED RESULT
No warning. The connected lambda is not capturing foo (only the nested lambda
is), so there's no risk.
SOFTWARE/OS VERSIONS
Windows: 21H1
Qt Version: Qt 5.15.2
clazy_v1.8-msvc2019.zip as build by KDAB (File lambda-in-connect.cpp has no
commits between 1.8 and master).
ADDITIONAL INFORMATION
If the connected lambda is capturing by reference something other than foo, the
warning should still not appear.
