alexcrichton opened PR #3823 from instantiate-many-less-memor to main:

Per-Store allocations are already limited with the StoreLimits
structure while fuzzing to ensure fuzz targets don't allocate more than
1GB of memory, but the instantiate-many fuzzer created many separate
stores which each had their own limit, meaning that the 2GB limit of
fuzzing could be pretty easily reached.

This commit fixes the issue by making StoreLimits a shareable type via
Rc to ensure the same limits can be applied to all stores created
within a fuzz run, globally limiting the memory even across stores to 1GB.
