May be. Or it may be a bug in some other part of the toolchain.

I don't have DJGPP tools at hand here at the university, otherwise
I'ld check your example case right away.  As is, I'd like to ask you
some things to check out for yourself.  Please ave a look at 'gcc -S
-fverbose-asm' output for both sourcefiles. Pay a particularly close
look at any occurance of 'head' in the '.stab' (debug info)
directives. 

If possible try to compare such dumps made with different versions of
the whole binutils suite (not just 'ld': 'as', too, at the minimum)
and gcc in place, and maybe also 'objdump -x' output of compiled
.o files (gcc -g -save-temps bug.c glob.c).

Even if all the snow were burnt, ashes would remain.
