------- Comment #12 from dave dot korn dot cygwin at gmail dot com 2009-03-25 08:03 ------- Hi all.
This patch caused g++.dg/ext/dllimport7.C to regress (in one subtest) between 4.3.2 and 4.3.3 on Cygwin, although it could be that the testcase is out of date. // { dg-do compile { target i?86-*-cygwin* i?86-*-mingw*} } // Report errors on definition of dllimport'd static data member . struct Baz { Baz(int a_ =0) : a(a_) {} int a; }; class __declspec(dllimport) Bar { public: enum {one = 1}; static const int two = 2; static const int three; static const Baz null_baz; }; const int Bar::three = 3; // { dg-warning "redeclared without dllimport" } // { dg-error "definition of static data" "C++ specific error" { target i?86-*-cygwin* i?86-*-mingw* } 21 } const Baz Bar::null_baz; // { dg-warning "redeclared without dllimport" } // { dg-error "definition of static data" "C++ specific error" { target i?86-*-cygwin* i?86-*-mingw* } 24 } int foo() { Bar foobar; const int* baz = &Bar::two; int a = foobar.two; int b = foobar.three; int c = foobar.null_baz.a; return (a + b + c + *baz); } Both the dg-error clauses now fail; previously (4.3.2), only the second one failed. Reverting the patch causes the first dg-error (line 21) to pass again by restoring the error message /gnu/gcc/release/gcc4-4.3.3-1/src/gcc-4.3.3/gcc/testsuite/g++.dg/ext/dllimport7. C:21: error: definition of static data member 'Bar::three' of dllimport'd class I'm not sure why that should be a problem in the first place, so I don't know if the underlying issue is now fixed and not an error any more.
