From 4f310faee0721d52bd9c68dac88c9169f09b5e72 Mon Sep 17 00:00:00 2001 From: Sami Kerola Date: Sun, 2 Nov 2014 22:06:15 +0000 Subject: build-sys: make scanf_cv_alloc_modifier to work [LeakSanitizer] The tests failed with following message in config.log ERROR: LeakSanitizer: detected memory leaks Direct leak of 2 byte(s) in 1 object(s) allocated from: #0 0x49a40e in realloc (/home/src/util-linux/conftest+0x49a40e) #1 0x7fbe48633e69 in __GI__IO_vfscanf (/usr/lib/libc.so.6+0x56e69) #2 0x7fbe48649786 in _IO_vsscanf (/usr/lib/libc.so.6+0x6c786) which knocked out libmount from build, and commands depending on it. The reason this change makes sense is that AddressSanitizer seems like a good addition to set of tools that util-linux package can use, when and if needed.
