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/expr/anew4.C | 44 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 gcc/testsuite/g++.dg/expr/anew4.C (limited to 'gcc/testsuite/g++.dg/expr/anew4.C') diff --git a/gcc/testsuite/g++.dg/expr/anew4.C b/gcc/testsuite/g++.dg/expr/anew4.C new file mode 100644 index 000000000..4ce1d8899 --- /dev/null +++ b/gcc/testsuite/g++.dg/expr/anew4.C @@ -0,0 +1,44 @@ +// { dg-do run } +// PR 11228: array operator new, with zero-initialization and a variable sized array. +// Regression test for PR +// Author: Matt Austern + +#include +#include +#include + +struct B +{ + B(); + int n; +}; + +B::B() +{ + n = 137; +} + + +struct D : public B +{ + double x; +}; + + +D* allocate(int n) +{ + void *p; + p = malloc(n * sizeof (D)); + memset (p, 0xff, n * sizeof(D)); + return new (p) D[n](); +} + +int main() +{ + const int n = 17; + D* p = allocate(n); + for (int i = 0; i < n; ++i) + if (p[i].n != 137 || p[i].x != 0) + abort (); + exit (0); +} -- cgit v1.2.3
