Hi! >From time to time, GHC causes various issues when building the unregistered compiler with -O2 optimization levels. The problems range from miscompiled code on m68k and sh4 to the assembler crashing on ia64 due to the generated code. In order to fix this, upstream contains a change with which reduces the optimization level for unregistered builds to -O1 [1]. I'm attaching a backported version of the patch. Please consider including it in the next upload. Thanks, Adrian -- .''`.
