Known troublespots

The 2.02 compiler has the following known deficiencies:

native code generator, x86:

The native code generator for x86 platforms is by default switched off, as the code the compiler produces with it enabled was discovered just before releaseing to be wonky. Rather than delay the release further, GHC on x86 platforms rely on `GCC' as their backend for now. Hopefully fixed soon.

Simplifier looping:

The simplifier(Glasgow-speak for optimiser) has been observed to get into a loop in one or two cases. If you should observe this, please report it as a bug - the work around is to turn off optimisation.

Undefined `*_vap_info' symbols:

If the linker complains about some undefined `*_vap_info' symbols when linking 2.02 compiled programs (very unlikely) - fix this by compiling the module where the references are coming from with `-fno-lambda-lifting'.
