From: reichelt@igpm.rwth-aachen.de To: gcc-gnats@gcc.gnu.org Subject: c++/6255: ICE with templatess Date: Thu, 11 Apr 2002 06:06:00 -0000 [thread overview] Message-ID: <20020411125716.9374.qmail@sources.redhat.com> (raw) >Number: 6255 >Category: c++ >Synopsis: ICE with templatess >Confidential: no >Severity: serious >Priority: medium >Responsible: unassigned >State: open >Class: ice-on-legal-code >Submitter-Id: net >Arrival-Date: Thu Apr 11 06:06:01 PDT 2002 >Closed-Date: >Last-Modified: >Originator: Volker Reichelt >Release: gcc 3.0.x, gcc 3.1 20020408 (prerelease) >Organization: >Environment: i686-pc-linux-gnu >Description: When compiling the following code I get an ICE: ----------------------------snip here------------------- template <class T> struct A { typedef int X; }; template <class T> struct B { typedef A<T> Y; void f (Y::X); }; template <class T, class T1, class T2, class T3> struct C : public B<T> { void g (Y::X); }; template class B<int>; ----------------------------snip here------------------- bug.cpp:2: warning: `typename A<T>::X' is implicitly a typename bug.cpp:2: warning: implicit typename is deprecated, please see the documentation for details bug.cpp:3: warning: `typename C<T, T1, T2, T3>::Y::X' is implicitly a typename bug.cpp:3: warning: implicit typename is deprecated, please see the documentation for details bug.cpp: In instantiation of `B<int>': bug.cpp:4: instantiated from here bug.cpp:2: internal error: Segmentation fault Please submit a full bug report, [etc.] It's a regression from 2.95.2 where the code compiled without error. With 3.0.x the warnings disappear. The ICE vanishes if I replace "Y::X" by "typename Y::X". So it's actually an ice-on-deprecated-code. The problem is the same as the reduced testcase in PR 3649. The original testcase compiles fine now, so that PR 3649 was closed. >How-To-Repeat: g++ -c bug.cpp >Fix: >Release-Note: >Audit-Trail: >Unformatted:
