Bug ID: 94024
Summary: Error message has misleading source location for
constructor member initialisation.
Product: gcc
Version: 9.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: cubitect at gmail dot com
Target Milestone: ---
The error messages resulting from some types of incorrect initialisation,
within a constructor's initialisation list, indicate the error location to be
at the last member initialisation rather than the affected member. According to
godbolt all version of g++ have this behaviour.
/// test code:
struct A {
A()
: a() // erroneous value-initialization of reference
, b(1i) // erroneous complex conversion
, c('a') // errors are incorrectly displayed at member c
{}
int &a;
int b;
char c;
};
/// <source>: In constructor 'A::A()':
/// <source>:5:12: error: value-initialization of reference type 'int&'
/// 5 | , c('a') // errors are incorrectly displayed at member c
/// | ^
/// <source>:5:12: error: cannot convert '__complex__ int' to 'int' in
initialization
