T3424 hangs with -fregs-graph
The -fregs-graph option causes rts/T3424 to hang. I waited 15+ minutes when compiling with inplace/ghc-stage2 before killing it; when run with the test suite after a similarly long time I get a compile failed (exit code 99) message. It passes when run in ghci or when using the default register allocator.
To reproduce: make TEST=T3424 EXTRA_HC_OPTIONS=-fregs-graph
