ICE with egcs-19990607 (gcc 2.95 branch)

[Andris Pavenis <andris at stargate dot astr dot lu dot lv>]

Trying to torture C++ compiler 
(gcc-2.95 19990607 (prerelease))
to reproduce problems with accessing class members found 
following internal compiler error. egcs-1.1.2 simply gives warning message
without ICE

bad.cc:27: warning: direct base `vector<int,allocator<int> >' inaccessible in `B' due to ambiguity
bad.cc: In method `B::B()':
bad.cc:54: Internal compiler error 980827.
bad.cc:54: Please submit a full bug report to `egcs-bugs@egcs.cygnus.com'.
bad.cc:54: See <URL:http://egcs.cygnus.com/faq.html#bugreport> for details.
