Hi, The following commit 97ef604e "G_numeric: fix numeric evaluation with trailing zeros and y != 1." breaks evaluation of G-polylogs with some arguments/ For instance: evalf( G({-1,1,-1,0},1) ); evalf( G({-1,-1,1,-1,0},1) ); evalf( G({-1,0,1,-1,0},1) ); evalf( G({-1,1,-1,-1,0},1) ); evalf( G({-1,1,-1,0,0},1) ); evalf( G({-1,1,-1,1,0},1) ); evalf( G({-1,1,0,-1,0},1) ); evalf( G({-1,1,1,-1,0},1) ); evalf( G({0,-1,1,-1,0},1) ); evalf( G({0,1,1,-1,0},1) ); results in exception: log_eval(): log(0) instead of the correct numerical value. With best regards, Valery Yundin.
