I think it's because when I do the target remote, the entry point is into a C routine, so the current language is c instead of c++. When the language is c++ then the breakpoint works as expected. -----Original Message----- From: Daniel Jacobowitz [mailto:drow@mvista.com] Sent: Wednesday, June 18, 2003 12:07 PM To: Mathews_Alex@emc.com Cc: gdb@sources.redhat.com Subject: Re: Breakpoint on class member function Well, if I can't get a test case I'm not sure how much help I can be. Let's see... Is "ptype foo" correct both before and after the "target remote"? Does it list foo1 as a member? If both are yes, you're going to have to debug the lookup routines yourself to see where the problem is.
