Below I've written a simple program called 'new2.cc' #include using namespace std; class X { int xx; public: X(int _xx) {xx = _xx;} void display(void) { cout << xx; }; }; int main(void) { X xobj(2); xobj.display(); // Line 15 } I compiled it as follows: g++ new2.cc -onew2 -g When I break it on line 15, I get the same problem as PR1766 http://sources.redhat.com/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gdb&pr=1766&return_url=http%3A%2F%2Fsources.redhat.com%2Fcgi-bin%2Fgnatsweb.pl%3Fdatabase%3Dgdb%26category%3Dc%252B%252B%26severity%3Dall%26priority%3Dall%26responsible%3Dall%26submitter_id%3Dall%26state%3Dall%26ignoreclosed%3DIgnore%2520Closed%26class%3Dall%26synopsis%3D%26multitext%3D%26columns%3Dcategory%26columns%3Dstate%26columns%3Dclass%26columns%3Dresponsible%26columns%3Dsynopsis%26displaydate%3DDisplay%2520Current%2520Date%26cmd%3Dsubmit%2520query%26sortby%3DResponsible%26.cgifields%3Ddisplaydate%26.cgifields%3Dignoreclosed%26.cgifields%3Doriginatedbyme%26.cgifields%3Dcolumns (gdb) b 15 Breakpoint 1 at 0x8048654: file new2.cc, line 15. (gdb) r Starting program: /home/hareesh/new2 warning: Unable to find dynamic linker breakpoint function. GDB will be unable to debug shared library initializers and track explicitly loaded dynamic code. Breakpoint 1, main () at new2.cc:15 15 X xobj(2); (gdb) n 16 xobj.display(); (gdb) inspect xobj.display() Breakpoint 1, main () at new2.cc:15 15 X xobj(2); The program being debugged stopped while in a function called from GDB. When the function (X::display()) is done executing, GDB will silently stop (instead of continuing to evaluate the expression containing the function call). My question is, how come GDB doesn't stop on other boxes when I inspect a member function and it stops on mine :( ? Thanks, Hareesh
