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/union2.C | 39 +++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 gcc/testsuite/g++.old-deja/g++.other/union2.C (limited to 'gcc/testsuite/g++.old-deja/g++.other/union2.C') diff --git a/gcc/testsuite/g++.old-deja/g++.other/union2.C b/gcc/testsuite/g++.old-deja/g++.other/union2.C new file mode 100644 index 000000000..5c2d7dcac --- /dev/null +++ b/gcc/testsuite/g++.old-deja/g++.other/union2.C @@ -0,0 +1,39 @@ +// { dg-do run } +// Bug: g++ crashed on empty initializers for unions. +// Bug: gcc and g++ didn't zero unions with empty initializers. +// Submitted by J"orn Rennecke + +extern "C" void exit (int); + +typedef union u +{ + union u *up; + void *vp; +} u; + +static u v = {}; + +void bar (u); +void baz (u); + +void foo() +{ + u w = {}; + u x = { &v }; + baz (x); + bar (w); +} + +void baz (u w) { } + +void bar (u w) +{ + if (w.up) + exit (1); +} + +int main () +{ + foo (); + return 0; +} -- cgit v1.2.3
