** Tags added: apport-collected
** Description changed:
Binary package hint: gcc-4.4
std::chrono::monotonic_clock in <chrono> can be defined differently
(typedef system_clock or proper monotonic_clock) based on the define
_GLIBCXX_USE_CLOCK_MONOTONIC.
The latter should be defined from the gcc configuration scrips based on
whether the clock_gettime supports monotonic clock or not.
Ubuntu Lucid obviously supports monotonic clock (see example below),
however _GLIBCXX_USE_CLOCK_MONOTONIC is not defined in
/usr/include/c++/4.4/x86_64-linux-gnu/bits/c++config.h.
