From e9e6894d4bda07037433dbf14b0cabc7273a1337 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Wed, 4 Mar 2015 15:55:44 +1100 Subject: [PATCH] Assemble: don't ignore the return value from stat. static checkers complain about that. So change the code to use 'fstat', as we really don't want to see an error here..
