Description
The following C++11 code crashes with a segmentation fault:
#include <thread> int main() { for (int i = 0; i < 32768; ++i) { std::thread t([] {}); t.join(); } return 0; }
Compile with:
g++ -std=c++0x
It affects i686-4.8.2-release-posix-dwarf-rt_v3-rev3.7z but is fixed in i686-4.8.2-release-posix-dwarf-rt_v3-rev4.7z and later.
