Unfortunately I don't have easy access to a similar Sergio> machine, so I would like to know if: Something fishy is going on that builder. I did a try run of my ubsan series and got many errors like this: (gdb) break check_vx /usr/include/c++/4.8.2/debug/vector: Error: attempt to subscript container with out-of-bounds index gdb: /home/dje/src/gcc-6-branch/libstdc++-v3/src/c++11/debug.cc:942: void {anonymous}::print_string({anonymous}::PrintContext&, const char*, const _Parameter*, std::size_t): Assertion `param_index < num_parameters' failed. However I think this should only happen if libstdc++ debug mode is enabled. (Is this correct? Maybe this is the error.) I did do some try runs in the past of libstdc++ debug mode. So, I am wondering if there could somehow be stale .o files around. I don't see how really -- I'd expect configure to make config.h, and for that to force a full rebuild. But it still looks suspicious. Tom
