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/opt/pr15054.C | 36 ++++++++++++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 gcc/testsuite/g++.dg/opt/pr15054.C (limited to 'gcc/testsuite/g++.dg/opt/pr15054.C') diff --git a/gcc/testsuite/g++.dg/opt/pr15054.C b/gcc/testsuite/g++.dg/opt/pr15054.C new file mode 100644 index 000000000..cfc48cf24 --- /dev/null +++ b/gcc/testsuite/g++.dg/opt/pr15054.C @@ -0,0 +1,36 @@ +// PR middle-end/15054 +// This used to abort due to overlapping stack temporaries. + +// { dg-do run } +// { dg-options "-O" } + +extern "C" void abort (void); + +struct pointer +{ + void* ptr; + + pointer(void* x = 0) : ptr(x) {} + pointer(const pointer& x) : ptr(x.ptr) {} +}; + +struct element +{ + int canary; + + element() : canary(123) { } + ~element() { pointer(); if (canary != 123) abort (); } +}; + +inline pointer +insert(const element& x) +{ + return pointer(new element(x)); +} + +int +main (void) +{ + insert(element()); + return 0; +} -- cgit v1.2.3
