Bug ID: 78770
Summary: error: 'bar' was not declared in this scope. note:
suggested alternative: 'bar'
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: safinaskar at mail dot ru
Target Milestone: ---
Consider this code:
struct foo
{
friend void
bar (void);
void baz (void)
{
bar ();
}
};
void
bar (void)
{
}
g++ gives very strange "suggestion":
gcrash.cpp: In member function 'void foo::baz()':
gcrash.cpp:8:5: error: 'bar' was not declared in this scope
bar ();
^~~
gcrash.cpp:8:5: note: suggested alternative: 'bar'
bar ();
^~~
bar
Error seems to be legit. Problem is in suggestion. g++ suggests to replace
"bar" with "bar". (???)
