Deepti, this seems to be hanging around GrowMemory. It may also be that the wasm side defines an infinite loop - could you take a look? Thanks!
Looks like this is a duplicate of issue- https://bugs.chromium.org/p/chromium/issues/detail?id=672181

Looks like it is a timeout issue - test runs fine on my system - it takes a while but completes, and does not hang.
