The following testcase (which is invalid, as A::B doesn't exist) causes trouble: ============================================= template<typename> struct A {}; template<typename T> void A<T>::B::foo() {} ============================================= GCC 2.95.3 correctly rejects the code, gcc 3.1 - 3.3.4 wrongly accept it, gcc 3.0.x, 3.4.0 and mainline segfault.
Confirmed. Note 3.0.4 ICE after an error message (the same as 2.95.3): tin:~/src/gnu/gcctest>~/ia32_linux_gcc3_0/bin/gcc pr15227.cc pr15227.cc:3: syntax error before `::' token pr15227.cc:3: confused by earlier errors, bailing out
Retargeting to 3.4.1, being a regression on that release branch.
