Package: libstdc++6 Version: 8.2.0-1 Severity: important With a program I'm working on, its run $ mpiexec -n 1 ./bin/server.exe : -n 1 ./bin/client.exe
both programs hang, with: #0 std::local_Rb_tree_decrement (__x=0x55f54daac538) at ../../../../../src/libstdc++-v3/src/c++98/tree.cc:99 #1 0x000055f54d04eba8 in xios::CReorderDomain::registerTrans() () #2 0x000055f54cf5953f in _GLOBAL__sub_I__ZN4xios14CReorderDomainC2Ev () The MPI nature of the code should be irrelevant (they're independent processes, not interacting at this point but running the same piece of code) This code works with g++ 7.3, but fails with 8.1/ 8.2 thanks Alastair -- System Information: Debian Release: 9.4 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: i386 (i686) Kernel: Linux 4.9.0-6-686-pae (SMP w/1 CPU core) Locale: LANG=en_IE.UTF-8, LC_CTYPE=en_IE.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to en_IE.UTF-8), LANGUAGE=en_IE.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to en_IE.UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libstdc++6 depends on: ii gcc-6-base 6.3.0-18+deb9u1 ii libc6 2.24-11+deb9u3 ii libgcc1 1:6.3.0-18+deb9u1 libstdc++6 recommends no packages. libstdc++6 suggests no packages. -- no debconf information
