I have not debugged nasm code on Linux, so I have no specific advice for 
you, but here are some general
info to help you along:

Hmm, maybe it is not the nasm format, but the debug information format 
that is the problem.  As on all
platforms, there are different file formats that compilers, assemblers 
etc. can use to tell debuggers which
code bytes in the output file correspond to which lines in your source 
code file and what the name of
that file is.

In the case of Linux/Unix/GNU tools it may also be mandatory to include 
NASM directives to mark the
beginning and end of each named function, as gdb seems to be overly 
focused on checking that
information before looking at anything real.

Anyway, most current Linux tools use the GNU DWARF debug information 
format, I don't know if NASM
includes DWARF information in its elf32 output files.
