--- Comment #4 from infinityintegral333 at gmail dot com --- Created attachment 64877 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=64877&action=edit same bug in std::student_t_distribution, more info in comments in file sample programme for std::student_t_distribution for small values the bug is easily overseen because the error produced is not that big, but as the original and new parameters drift further away, the error becomes more obvious
