From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/g++.dg/inherit/covariant17.C | 43 ++++++++++++++++++++++++++++++ 1 file changed, 43 insertions(+) create mode 100644 gcc/testsuite/g++.dg/inherit/covariant17.C (limited to 'gcc/testsuite/g++.dg/inherit/covariant17.C') diff --git a/gcc/testsuite/g++.dg/inherit/covariant17.C b/gcc/testsuite/g++.dg/inherit/covariant17.C new file mode 100644 index 000000000..b2de15f7e --- /dev/null +++ b/gcc/testsuite/g++.dg/inherit/covariant17.C @@ -0,0 +1,43 @@ +// PR c++/43120 +// { dg-do run } + +extern "C" void abort (); + +struct A { + int a; + + A(int a_) : a(a_) {} + + A(const A &other) { } + + virtual void dummy() {} +}; + +struct B { + virtual B *clone() const = 0; +}; + +struct C : public virtual B { + virtual C *clone() const = 0; +}; + +struct E* ep; +struct E : public A, public C { + E(int a_) : A(a_) { ep = this; } + + virtual E *clone() const { + if (this != ep) + abort(); + return 0; + } +}; + +int main() { + E *a = new E(123); + C *c = a; + B *b = a; + c->clone(); + b->clone(); + delete a; + return 0; +} -- cgit v1.2.3
