[compiler-rt] r266931 - [asan] Add __strdup interceptor.

[Evgenii Stepanov via llvm-commits]

Hi,

it's hard to say w/o seeing the full output, but it looks like the
allocation stack trace is
 #0 0x60e8f in strdup
/home/linaro/buildbot/clang-cmake-armv7-a15-full/llvm/projects/compiler-rt/lib/asan/asan_interceptors.cc:560
  #1 0xe9e1f in _fini
(/home/linaro/buildbot/clang-cmake-armv7-a15-full/stage1/projects/compiler-rt/test/asan/ARMHFLinuxConfig/TestCases/Output/strdup_oob_test.cc.tmp+0xe9e1f)

which does not make any sense. This problem can't be reproduced on
arm-android. I can add an UNSUPPORTED line
(armv7l-unknown-linux-gnueabihf, is it?), but it looks like a genuine
problem with stack unwinding on arm.
