- There is a bug in the SGI compiler's optimization that causes a
- bus error in PyComplex_ImagAsDouble(); this has been reported to
- be triggered when importing Numeric Python and may be caused at
- other times. The work-around is to build Python, delete the
- Objects/complexobject.o file, and then recompile without
- optimization (use "make OPT=").
+ WARNING: There are bugs in the optimizer of some versions of
+ SGI's compilers that can cause bus errors or other strange
+ behavior, especially on numerical operations. To avoid this,
+ try building with "make OPT=".
