    Possible bug with bss allocation —Dave Baum
   I was having some random hangs with a legOS program. If I added a little code or subtracted a little, everything started working again. I've isolated it to a problem whereby writing a zero to the last byte of bss data will hang the RCX. This only (...) (24 years ago, 22-Jul-00, to lugnet.robotics.rcx.legos)
   
        Re: Possible bug with bss allocation —Eddie C. Dost
   (...) The common section is aligned to 16 bytes by ld. This is unknown to the tools generating the final .lx files. The fix is to force the alignment of the .bss section to 2, with this ld will generate files that work with the current tools. I (...) (24 years ago, 22-Jul-00, to lugnet.robotics.rcx.legos)

        Re: Possible bug with bss allocation —Eddie C. Dost
   (...) I have a proposal to the legOS developers: The current tool chain to generate executables for legOS is a little off: We generate coff-h8300 from .c or .S sources, next ld generates symbolsrec relocated files from that. This step is done twice (...) (24 years ago, 22-Jul-00, to lugnet.robotics.rcx.legos)

   (...) Paolo and others: Eddie and I have talked about this, and we both agree that this is a big change- so I think we are aiming for this for 0.2.5.

Generally, user programs have it pretty simple for this already (which is why I had thought of this some time ago, and then dismissed it.) I had never considered the (...)
