[Bug 610992] Re: clang -fstack-protector fails to link (undefined reference to `__stack_chk_guard')

[Launchpad Bug Tracker]

This bug was fixed in the package llvm-2.7 - 2.7-4ubuntu1

---------------
llvm-2.7 (2.7-4ubuntu1) maverick; urgency=low

  [ Matthias Klose ]
  * Merge with Debian; remaining changes:
    - Don't build llvm-2.7-priv-dev, remove build dependency on
      llvm-2.7-priv-dev.
    - Adjust conflicts with unversioned llvm package as found in lucid.
  * Replace 0010-ARM-BX_to_BLX.patch by 0010-r109125.patch.  ARMv4 JIT forgets
    to set the lr register when making a indirect function call. Fixes PR7608.
  * Backports from 2.8 (taken from OpenEmbedded):
    - 0041-r104558-VFPmisc.patch: Add missing implementation to the
      materialization of VFP misc. instructions (vmrs, vmsr and vmov
      (immediate)).
    - 0042-r104587-MOVimm32.patch: Fix TestARMCodeEmitter::emitPseudoInstruction
      UNREACHABLE at ARMCodeEmitter.cpp:554.
    - 0043-r104652-VFPLoadStoreMultiple.patch: Fix PR7221, makes VFP
      calculations correct.
    - 0044-r104653-BFC-BFI.patch: Fix PR7222, ERROR: ARMv6t2 JIT is not yet
      supported.
  * Configure with --with-optimize-option=, always build in ARM mode on armel.

  [ Anders Kaseorg ]
  * debian/patches/0032-x86-fast-isel-fs-load.patch,
    debian/patches/0033-stack-protector-linux.patch: Take upstream r106031
    and r107640 to fix clang -fstack-protector link errors.  (LP: #610992)
