From b690801c78e33e1d7a8e54fe4d06f300bfa518b4 Mon Sep 17 00:00:00 2001 From: Bernhard Reutner-Fischer Date: Sat, 25 Aug 2007 11:22:51 +0000 Subject: This patch fixes a bug into ostream::operator<<(double) due to the wrong size passed into the __convert_from_v method. The wrong size is then passed to std::snprintf function, that, on uClibc, doens't handle sized 0 buffer.
