State-Changed-From-To: open->analyzed State-Changed-Why: Confirm. From: Volker Reichelt <reichelt@igpm.rwth-aachen.de> To: gcc-gnats@gcc.gnu.org, dmonksfd@broadcom.com, gcc-bugs@gcc.gnu.org Cc: Subject: Re: c++/7083: [2003-01-22] ICE using -gstabs with dodgy class derivation Date: Tue, 06 May 2003 18:17:47 +0200 (CEST) GCC crashes at least since 2.95.x on the code. This affects also 3.3 branch and mainline as of 2003-05-06. BTW, the code looks legal to me. Regards, Volker http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=7083 *** Bug 8446 has been marked as a duplicate of this bug. *** This also fails in 3.2.2 and 3.2.3. |
