--- Comment #1 from Ben Woodard <woodard at redhat dot com> ---
Another version of what I think is the same problem is:

hype260@ben:cat
collab/usr/global/tools/order/spack/opt/chaos_5_x86_64_ib/gcc@4.4.7/lcms@2.6-cc59eee2/lib/liblcms2.so.2.0.6/stderr

1 function with some indirect sub-type change:

  [C]'function void _cmsInstallAllocFunctions(cmsPluginMemHandler*,
_cmsMemPluginChunkType*)' has some indirect sub-type changes:
    parameter 1 of type 'cmsPluginMemHandler*' has sub-type changes:
      in pointed to type 'typedef cmsPluginMemHandler':
        underlying type 'struct __anonymous_struct__' changed:
          2 data member changes:
           type of '_cmsMallocFnPtrType __anonymous_struct__::MallocPtr'
changed:
             underlying type 'void* ()*' changed:
               in pointed to type 'function type void* (typedef cmsContext,
typedef cmsUInt32Number)':

           type of '_cmsMalloZerocFnPtrType
__anonymous_struct__::MallocZeroPtr' changed:
             underlying type 'void* ()*' changed:
               in pointed to type 'function type void* (typedef cmsContext,
typedef cmsUInt32Number)':

    parameter 2 of type '_cmsMemPluginChunkType*' has sub-type changes:
      in pointed to type 'typedef _cmsMemPluginChunkType':
        underlying type 'struct __anonymous_struct__' changed:
          2 data member changes:
           type of '_cmsMallocFnPtrType __anonymous_struct__::MallocPtr'
changed:
             underlying type 'void* ()*' changed:
               in pointed to type 'function type void* (typedef cmsContext,
typedef cmsUInt32Number)':

           type of '_cmsMalloZerocFnPtrType
__anonymous_struct__::MallocZeroPtr' changed:
             underlying type 'void* ()*' changed:
               in pointed to type 'function type void* (typedef cmsContext,
typedef cmsUInt32Number)':



1 Changed variable:

  [C]'_cmsMemPluginChunkType _cmsMemPluginChunk' was changed:
    type of variable changed:
     underlying type 'struct __anonymous_struct__' changed, as reported earlier

When this bug is fixed for libtiff I'll go back and retest with liblcms2.
