From eb5e4a247666c0ba26b21e214249789ea7c52e85 Mon Sep 17 00:00:00 2001 From: James McCoy Date: Sat, 6 May 2017 22:35:50 -0400 Subject: *: Disable UBSAN for VimL arithmetic implementation After merging +num64, the 64-bit sanitizer builds show that Vim doesn't buffer the user from C's UB in signed arithmetic. Upstream doesn't appear to be [interested] in fixing the issue, so suppress UBSAN until someone decides to fix the problem. N.B., the problem existed before but went unnoticed since the sanitizer builds weren't being run in 32-bit mode.
