Hi!

I'm running Mac OS X 10.9.3, Chromium-trunk (revision 
4263ed728d4582468c6a01ce568896c322a7aafd / r267101). Bundled clang version 
3.5.0 (trunk 206824).

$ echo $GYP_DEFINES
disable_nacl=1 asan=1 component=shared_library

Here's the full ASAN report: https://gist.github.com/mblsha/b9945027470eaa9ffb10

Excerpt:
==85253==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x43d3bc78 at 
pc 0xafe47 bp 0xbff75f88 sp 0xbff75b6c

    #3 0x9a5fa49b in clEnqueueNDRangeKernel (in OpenCL) + 182

As it happens inside OpenCL, is there any way to blacklist it?

x86_64 Chromium build works fine, the problem only happens with i386 build.
