·Some assertions checked by Debug Mode can now also be enabled by _GLIBCXX_ASSERTIONS. The subset of checks enabled by the new macro have less run-time overhead than the full _GLIBCXX_DEBUG checks and don't affect the library ABI, so can be enabled per-translation unit. ·Timed mutex t...
the "do_bar ();" looks like it's guarded by the conditional, but it's actually outside of it. Similarly, in this code fragment: for (i = 0; i < n; i++) sum[i] = a[i] + b[i]; prod[i] = a[i] * b[i]; the computation of prod[i] is actually outside of the loo...
