Bug ID: 90590
Summary: enumeration value not handled in switch warning for
std::ios_base::seek_dir
Product: gcc
Version: 9.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: alan at birtles dot org.uk
Target Milestone: ---
GCC (and clang bug 67996) raises a warning when declaring a switch statement
which uses std::ios_base::seek_dir.
The following:
#include <iostream>
int main()
{
std::ios_base::seekdir dir = std::ios_base::end;
switch ( dir )
{
case std::ios_base::end:
case std::ios_base::beg:
case std::ios_base::cur:
break;
}
}
produces:
test.cpp: In function 'int main()':
test.cpp:6:12: warning: enumeration value '_S_ios_seekdir_end' not handled in
switch [-Wswitch]
