Gdb on my system is behaving abruptly.
Say if your program has some 10 lines of code in a function in your program.
Code are simple statements with no looping or jumps.
Example:
Say you put breakpoint at fn() start.
Your breakpoint hits and then say after debugging(using next/n gdb command) till 3 lines in the function the gdb shows directly the line say 7th line which it must not. Note that gdb does not execute the statement at that line.
Press again next and it will show properly 4th line now.
Why gdb is behaving so and how to make it normal?
GDB is GNU gdb (GDB) SUSE (7.3-0.6.1)
OS is SLES 64 bit.

These files contain GDB commands to automatically execute during GDB startup. The lines of contents are canned sequences of commands,
described in the GDB manual in node "Sequences" -- shell command "info -f gdb -n Sequences".
Please read more in the GDB manual in node "Startup" -- shell command "info -f gdb -n Startup".
/etc/gdbinit
System-wide initialization file. It is executed unless user specified GDB option "-nx" or "-n". See more in the GDB manual in node
"System-wide configuration" -- shell command "info -f gdb -n 'System-wide configuration'".
~/.gdbinit
User initialization file. It is executed unless user specified GDB options "-nx", "-n" or "-nh".
./.gdbinit
Initialization file for current directory. It may need to be enabled with GDB security command "set auto-load local-gdbinit". See
more in the GDB manual in node "Init File in the Current Directory" -- shell command "info -f gdb -n 'Init File in the Current

The full documentation for GDB is maintained as a Texinfo manual. If the "info" and "gdb" programs and GDB's Texinfo documentation are
properly installed at your site, the command
info gdb
should give you access to the complete manual.
