To: vim-dev@vim.org Subject: Patch 6.0.160 Fcc: outbox From: Bram Moolenaar MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 8bit ------------ Patch 6.0.160 Problem: When compiling with GCC 3.0.2 and using the "-O2" argument, the optimizer causes a problem that makes Vim crash. Solution: Add a configure check to avoid "-O2" for this version of gcc.
