System Information
Arch linux 3.11.6 (64 bit)
NVidia GTX 660

Blender Version
Broken: 2.69.10, e996b88
Worked: unknown

Short description of error
Blender built with clang in Debug mode crashes with heap memory errors in several cases.

Exact steps for others to reproduce the error

2 cases i found so far below. Both of these work fine in GCC/Debug, but fail in clang/Debug. Release mode also works fine with both compilers.

Case 1: Scene unlink

  • Add new scene
  • In new scene: enable compositing nodes ("use nodes")

Unlink scene (info space "x" button)

scene_unlink_crash.blend

Address sanitizer report: P13: address sanitizer report from scene unlink crash

Case 2: Boolean modifier

Requires carve API patch D274

  • Get D274
  • Make a UV sphere in addition to default cube
  • On default cube: Add boolean modifier
  • Set bool modifier Object to the sphere, let them intersect
    bool_mod_crash.blend

Address sanitizer report: P14: address sanitizer report from boolean modifier crash
