Current GCC mainline ICEs, instead of reporting errors, for test
g++.dg/old-deja/g++.benjamin/13908.C on powerpc-linux.  The test
isn't reported as failing because dg-error is used with a blank
string.  The ICE starts with the following patch, which might
merely expose a latent bug:
                                                                                
  http://gcc.gnu.org/ml/gcc-cvs/2005-04/msg00325.html
                                                                                
Test output:
                                                                                
13908.C: In function ‘void bar(chile*, void (chile::*)())’:
13908.C:20: error: parenthesis around ‘pobj->*pmethod’ cannot be used to form a
pointer-to-member-function
13908.C:20: internal compiler error: tree check: expected class ‘type’, have
‘declaration’ (function_decl) in build_offset_type, at tree.c:4628
