Richard Smith 6d9f13127c ubsan: Add checking for invalid downcasts. Per [expr.static.cast]p2 and p11, 
base-to-derived casts have undefined behavior if the object is not actually an
instance of the derived type. Runtime library part.

Alexander Potapenko c5ba5ef3c5 [ASan] When re-executing the process on OS X, make sure we update the existing DYLD_INSERT_LIBRARIES correctly. 
Previously ASan used to hang in an exec loop, because it failed to overwrite the env var value
(see https://code.google.com/p/address-sanitizer/issues/detail?id=159).

Kostya Serebryany 2659e96e4b [asan] change the default mapping offset on x86_64 to 0x7fff8000. This gives roughly 5% speedup. Since this is an ABI change, bump the asan ABI version by renaming __asan_init to __asan_init_v1. compiler-rt part

 2013-02-08 11:19:23 +00:00
Evgeniy Stepanov 87c43537df [sanitizer] Improve scanf interceptor 
This a rewrite of the scanf parser. The new implementation is pretty close to
the spec, with a few shortcuts taken here and there. It is conservative, i.e.
it gives up parsing if it does not understand some part of the format string,
or runs into an ambiguous % spec. It does not handle some rarely used parts of
the spec, like %n$ - for now.

I'm also moving parser call to after the original *scanf function completes,
so that we can find out the store size of %s directive by the use of strlen()
on the target buffer.

Alexander Potapenko 4fb43438d9 [ASan] Enable the new and delete wrappers on Darwin.

Alexander Potapenko d895ae94f9 Use 64-bit inodes in file operations. ASan is now built with -mmacosx-version-min=10.5, thus the default inode

where X was actually inside [A, B).

With this change, ASan will report B as the error address in such case.
