I'm trying to debug a small program I've written in C. I open up the file in emacs, M-x gdb, give the program filename (a.out). When i switch to the source file in the emacs pane, and try to place a breakpoint in the main function, I get the message "No default breakpoint address now." and the breakpoint doesn't place, so I can't debug the program. I'm compiling the program with the options gcc -Wall -ansi -pedantic-errors -Werror. Any ideas?

I compiled GDB 7 on a Mac OS X Leopard system. When stepping through a C program, GDB fails to step through 'printf()' statements, which probably don't have associated debug information, and starts printing "Cannot find bounds of current function." Here's some output: $ /usr/local/bin/gdb try1 GNU… >>> More
