- Subject: [patch] testsuite: new: std::terminate crash
Hi,
this is a testcase for a checked-in fix:
Re: RFC: fix bug with std::terminate handler
http://sourceware.org/ml/gdb-patches/2010-03/msg00861.html
Message-ID: <m339zodtow.fsf@fleche.redhat.com>
93ad27bbc56b9c0209d9b49851d538afc80723dd
http://sourceware.org/ml/gdb-cvs/2010-03/msg00242.html
Tested on {x86_64,x86_64-m32}-fedora14snapshot-linux-gnu.
I am not sure how useful it is for FSF GDB but I had to write it anyway.
Thanks,
Jan
