Bug ID: 58909
Summary: C++11's condition variables fail with static linkin
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: joel at clambassador dot com
The program:
#include <condition_variable>
int main () { std::condition_variable a; }
statically compiled as either:
g++ --std=c++0x -static -pthread aa.cc -lpthread
clang++ --std=c++11 -static -pthread aa.cc -lpthread
segfaults at the destructor's implicit call to pthread_cond_destroy(). Other
uses of std::condition_variable also fail. nm shows that pthread_cond_*
functions are only 'w', while programs that use other aspects of c++ threading,
such as mutexes, will have 'W' pthread_mutex_* and corresponding "T"
__pthread_mutex_* available.
