It's been a while, but I have. It was the Microsoft Basic Compiler
Version 6 (The one between QB4.5 & PDS). Someone else & I spent about
a week isolating the problem and developing a small program that
showed the error. It worked on the previous version, and failed on
version 6. It was reported to MS and that's the last we ever heard.


And, of course, there is the well known bug in MASM 6:
  ...
  .data? (.bss space - not initialized)
  foo db 500000 dup (?)
  ...
Works, but takes forever. :-) But that's an assembler. :-)




As well as any bugs in BCET, but that's my problem. :-)
