Instead, the compiler fails with error message: $ g++ -std=c++0x -c 2.cpp `pkg-config --cflags python3` 2.cpp: In function ‘void init_from_tuples_impl(S)’: 2.cpp:23:1: internal compiler error: in lower_stmt, at gimple-low.c:428 Please submit a full bug report, with preprocessed source if appropriate. See <https://bugs.archlinux.org/> for instructions. (It should be possible to remove the dependency on Boost.Python, but I haven't have time to do so yet). gcc config: $ g++ -v Using built-in specs.
