I was having some random hangs with a legOS program. If I added a little code or subtracted a little, everything started working again.

(...) 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)
