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/eh/stabilize.C | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100644 gcc/testsuite/g++.dg/eh/stabilize.C (limited to 'gcc/testsuite/g++.dg/eh/stabilize.C') diff --git a/gcc/testsuite/g++.dg/eh/stabilize.C b/gcc/testsuite/g++.dg/eh/stabilize.C new file mode 100644 index 000000000..df47cab0c --- /dev/null +++ b/gcc/testsuite/g++.dg/eh/stabilize.C @@ -0,0 +1,26 @@ +// PR c++/8186 + +// Bug: In f, convert_for_arg_passing wrapped the A TARGET_EXPR in an +// ADDR_EXPR for passing by invisible ref. stabilize_throw_expr copied the +// resulting pointer into a temporary. cp_convert_parm_for_inlining then +// dereferences it and tries to initialize B::am with the INDIRECT_REF, +// which calls for a bitwise copy.
