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++.old-deja/g++.other/singleton.C | 39 ++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 gcc/testsuite/g++.old-deja/g++.other/singleton.C (limited to 'gcc/testsuite/g++.old-deja/g++.other/singleton.C') diff --git a/gcc/testsuite/g++.old-deja/g++.other/singleton.C b/gcc/testsuite/g++.old-deja/g++.other/singleton.C new file mode 100644 index 000000000..2a27ca3cd --- /dev/null +++ b/gcc/testsuite/g++.old-deja/g++.other/singleton.C @@ -0,0 +1,39 @@ +// { dg-do run } +// This tests two things: +// 1. there is an annoying warning. +// singleton.C:26: warning: `class singleton' only defines private constructors and has no friends +// egcs fails to see that there is a public static accessor function. +// 2. the program crashes, because apparently the static variable s in +// singleton::instance() is considered constructed although the ctor +// exited via an exception.
