Summary: internal compiler error: in gimplify_var_or_parm_decl, at gimplify.c:1946 Product: gcc Version: 4.4.5 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: hea...@gmail.com Created attachment 23878 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=23878 The failing source file I compile the attached file using this command: $ g++ -std=gnu++0x -Wall -Wextra -c test.cpp with this version of GCC: $ gcc --version gcc (Gentoo 4.4.5 p1.2, pie-0.4.5) 4.4.5 Copyright (C) 2010 Free Software Foundation, Inc.

I get this output: test.cpp: In member function ‘void Sender::flush()’: test.cpp:168: internal compiler error: in gimplify_var_or_parm_decl, at gimplify.c:1946 Please submit a full bug report, with preprocessed source if appropriate. See <http://bugs.gentoo.org/> for instructions. I also have access to an OpenSUSE x86-64 environment reading out this version: $ gcc --version gcc (SUSE Linux) 4.5.0 20100604 [gcc-4_5-branch revision 160292] Copyright (C) 2010 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. This gives the following output: test.cpp: In member function ‘void Sender::flush()’: test.cpp:175:71: internal compiler error: in gimplify_var_or_parm_decl, at gimplify.c:1816 Please submit a full bug report, with preprocessed source if appropriate. See <http://bugs.opensuse.org/> for instructions. (yes, the source line number of the error in test.cpp is different for this GCC version even though the sources are identical). Finally, a friend using Arch Linux x86-64 tested the same code on GCC 4.6 and also reproduced the bug, though I don't have the line numbers from that test. I can attach preprocessed source if you want, though the source doesn't use anything but standard headers and the problem seems quite easily reproducible as I already described.
