Bug #: 56835
Summary: std::promise seems broken on 10.8 lion
Classification: Unclassified
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: verdagon@gmail.com
Hi all, the following code crashes on 10.8 lion.
#include <future>
#include <iostream>
int main() {
std::cout << "doing the test" << std::endl;
std::promise<bool> mypromise;
std::future<bool> myfuture = mypromise.get_future();
mypromise.set_value(true);
bool result = myfuture.get();
std::cout << "success, result is " << result << std::endl;
return 0;
}
with this output:
$ g++-mp-4.8 -std=c++11 test.cpp
$ ./a.out
doing the test
Segmentation fault: 11
$
more info:
gcc version 4.8.0 20130310 (experimental) (MacPorts gcc48 4.8-20130310_0)
I'm on a Mac OS 10.8 (mountain lion)
compiled with: g++-mp-4.8 -std=c++11 test.cpp
(though I've tried with -lpthread and -pthread and they also crashed)
No compiler output, compiled just fine.
(see

You were asked to find where it crashes:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56822#c1
You were asked to read http://gcc.gnu.org/bugs and provide the requested
information, which is still missing e.g. the output of 'gcc -v'

I can't reproduce this crash with the fink build of gcc 4.8.0 on
x86_64-apple-darwin12. Notice that MacPorts is building the their gcc48 package
with additional change of...
https://trac.macports.org/browser/trunk/dports/lang/gcc48/files/libstdc%2B%2B-configure-timespec.patch
to get the _GLIBCXX_USE_CLOCK_MONOTONIC defined in config.h. This is claimed to
be in order to get libstdc++ to use nanosleep. However, a different fix was
checked in...

Jonathan Wakely <jwakely.gcc@gmail.com>
* config/os/bsd/darwin/os_defines.h: Define _GLIBCXX_USE_NANOSLEEP
and _GLIBCXX_USE_SCHED_YIELD.
* acinclude.m4 (GLIBCXX_ENABLE_LIBSTDCXX_TIME): Add comment.
which results in nanosleep being used on darwin by default...

% nm thread.o | grep nanosleep
U _nanosleep

IMHO, this should be closed as invalid since MacPorts is applying unnecessary
and invalid patches to gcc 4.8.0.
