From 5efbbca8188abba6a3a3a3eea07afb3f824a806e Mon Sep 17 00:00:00 2001 From: Evgeniy Stepanov Date: Tue, 21 Oct 2014 21:08:13 +0000 Subject: [PATCH] [sanitizer] Fix build with _FILE_OFFSET_BITS=64. Sanitizer source is not affected by _FILE_OFFSET_BITS in general, but this one file must be built with 32-bit off_t.
