Just use 9.2 or higher to analyse memory, there is no reason to support analysis in older versions |

The memory profiling scheme was added by @mpardalos. It works by stopping the world and traversing the heap using the
heapsizepackage, but it breaks if a GC starts halfway, leading to a segfault.Nowadays we have a better tool for this sort of analysis, ghc-debug, which snapshots the heap and performs the analysis offline.
