Bug ID: 100117
Summary: FAIL testsuite/17_intro/headers/c++1998/49745.cc with
trunk glibc
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org
Target Milestone: ---
I have seen (with r11-7986 , so sorry if it has been fixed already)
FAIL: 17_intro/headers/c++1998/49745.cc (test for excess errors)
which appears only when built against latest glibc 2.34 snapshot and works fine
against glibc 2.33.
libstdc++.log contains:
/builddir/build/BUILD/gcc-11.0.1-20210405/libstdc++-v3/testsuite/17_intro/headers/c++1998/49745.cc:22:
error: 'int truncate' redeclared as different kind of entity

/usr/include/unistd.h:1005: note: previous declaration 'int truncate(const
char*, __off_t)'
Maybe it would be nice if bits/sigstksz.h didn't include whole unistd.h but
just
bits/confname.h and used some __ prefixed alias with redirection for the
sysconf call?
