I have recently upgraded from FreeBSD 3.1 to 4.3-20010525-STABLE.
I wrote a very simple assembly language program that was giving me
a bus error. For several hours I have been trying to find what was
wrong with it, but could not.
Finally, out of desperation, I moved uninitialized data from .bss
to .data, and suddenly the program worked without a problem.
This puzzled me, so I used ld on an older program of mine, one of
the programs from my assembly language tutorial
(http://www.int80h.org/bsdasm/). It started giving me the same
bus errors. The version I created under 3.1 continues to work
fine.
That tells me something has changed in the way ld handles the .bss
section between 3.1 and 4.3 - either on purpose or as a bug.
This completely invalidates my assembly language tutorial. If the
change was on purpose, can someone please tell me what new switch
I need to use with ld to recognize the .bss section as being bss?
Thank you,
Adam
