Description

We have `HeapMaxSize` set to 10 MiB. When we try to allocate more than 10 MiB we get `SIGILL`. Is there a nice way to catch and recover from these type of rogue allocations?

Research direction

The issue names no files or tests. Start by reproducing the allocation with HeapMaxSize set to 10 MiB, then trace the SDK's allocation failure and SIGILL handling path. Done means establishing and documenting a recoverable behavior for allocations exceeding the configured limit, or clearly identifying the limitation.
