Bug#904998: libstdc++6: libtsdc++ with g++-8 hangs in std::local_Rb_tree_decrement
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
