From: Reichelt <reichelt@igpm.rwth-aachen.de> To: gcc-gnats@gcc.gnu.org, dwelter@sfwmd.gov, gcc-bugs@gcc.gnu.org, nobody@gcc.gnu.org Cc: Subject: Re: c++/7737: g++ ver 3.2 Internal Compiler Error Date: Wed, 28 Aug 2002 15:21:50 +0200 Hi, the problem can be demonstrated with the following code snippet: -----------------------------snip here---------------------------- struct A { void foo(); }; void bar () { &(A::foo); } -----------------------------snip here---------------------------- which is in fact illegal code. One should write "&A::foo" instead of "&(A::foo)". In the original code you have to replace "&(Wall::...Flow)" by "&Wall::...Flow" in the functions "Cell::OLVector()", "Cell::GWVector()" and "Cell::TotalVector()" to make things compile. The failures of gcc with the code snippet are quite interesting: * With gcc 2.95.x the code compiles using "g++ -c" (even with "-pedantic" turned on), which is wrong. * With gcc 3.0.x I get the error message PR7737.cc: In function `void bar()': PR7737.cc:2: warning: statement cannot resolve address of overloaded function which is bogus * With 3.1 and 3.2 I get an ICE: PR7737.cc: In function `void bar()': PR7737.cc:2: Internal compiler error in resolve_offset_ref, at cp/init.c:1886 However with the main trunk (gcc 3.3 20020816) I get the right diagnostic: PR7737.cc: In function `void bar()': PR7737.cc:2: error: parenthesis around 'A::foo()' cannot be used to form a pointer-to-member-function Greetings, Volker Reichelt http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=7737
