Classification: openSUSE Product: openSUSE 11.3 Version: Final Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Development AssignedTo: pth@novell.com ReportedBy: malcolm.douglas@gmail.com QAContact: qa@suse.de Found By: --- Blocker: --- Created an attachment (id=432692) --> (http://bugzilla.novell.com/attachment.cgi?id=432692) C++ source file that causes g++ to bug out. User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/534.24 (KHTML, like Gecko) Chrome/11.0.696.68 Safari/534.24 When compiling attachment with the command: g++ -ftemplate-depth=4496 -o submission submission.cc I get a segfault. Doesn't segfault with -ftemplate-depth=4495, in that case I get an error saying I'm above the recursive depth for templates, and that I need to increase it. On my system I guess this is the breaking point. Reproducible: Always Steps to Reproduce: 1.try to compile the attached source code with the command source code. The command I used is: g++ -ftemplate-depth=4496 -o submission submission.cc 2.If it doesn't seg fault on your system, maybe try to increase the -ftemplate-depth and add a bigger integer to check the primeness of in the source code in the main function. My system is: gcc -v : Using built-in specs.

Actual Results: g++ -ftemplate-depth=4496 -o submission submission.cc g++: Internal error: Segmentation fault (program cc1plus) Please submit a full bug report. See http://bugs.opensuse.org/ for instructions. Compilation exited abnormally with code 1 at Thu Jun 2 11:11:04 Expected Results: Segfaults! Eep! Might be upstream though, don't have an upstream gcc to try it on. I don't really care about this at present because I was just experimenting with template meta-programming. That being said, in my case it was pretty easy to determine the cause of the segfault, which I suppose isn't always true. Since this can be caused by an increased constant in a parameter of the template, and sometimes template stuff gets buried by typedefs and inheritance, this might be hard to pinpoint in a larger project. And the error message said to report the bug, so I figured I would do so. But as far as I'm concerned it's not important. I will respond to follow up correspondence if I can help, however. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
