Bug ID: 61940
Summary: Wrong error location for error in initialization list
Product: gcc
Version: 4.8.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: martin at steghoefer dot eu

Example that provokes an error message with a wrong location
When using several initializers in a constructor initializer list, an error in
one of the initializers (e.g. a conversion from a const pointer to a non-const
pointer, like in the attached example) is reported by gcc on the last token of
the *whole* initializer list (not the last token of the erroneous initializer).
This behavior is independent of the erroneous initializer being a member
initialization or a call to a super-class constructor.
Reproduce:
g++ gcc-wrong-error-location.ii
Output:
gcc-wrong-error-location.cxx: In constructor ‘Class::Class(const double*)’:
gcc-wrong-error-location.cxx:13:19: error: invalid conversion from ‘const
double*’ to ‘double*’ [-fpermissive]
m_otherMemberB(1) // good initialization (shown as erroneous
line)
