------------------------------+---------------------------------------------
 libs/random/src/random_device.cpp uses strerror function which is not
 thread-safe on many platforms (e.g. Linux). Its use should be replaced
 with strerror_r, when possible. Also, the way errno is used is not correct
 because it may be changed while the error string is composed.

 The suggested solution would be to use system_error from Boost.System
 instead of invalid_argument. The possible errors don't look like are
 caused by an invalid argument anyway. The Boost.System implementation
 already uses strerror_r when possible, so the switch to system_error would
 resolve the problem.
