nofib’s cacheprof’s allocations nondeterminisitic
This seems to be neither expected nor desired, and hence worth investigating:
./cacheprof +RTS -t
<<ghc: 127588752 bytes, 243 GCs, 2261288/6551032 avg/max bytes residency (6 samples), 15M in use, 0.00 INIT (0.00 elapsed), 0.12 MUT (0.12 elapsed), 0.05 GC (0.05 elapsed) :ghc>>
./cacheprof +RTS -t
<<ghc: 127392144 bytes, 242 GCs, 2261304/6551576 avg/max bytes residency (6 samples), 15M in use, 0.00 INIT (0.00 elapsed), 0.11 MUT (0.11 elapsed), 0.04 GC (0.05 elapsed) :ghc>>The allocations numbers change, when they shoudn’t.
Reproduced with 7.6.3 and current HEAD.
