fix failing tests in debug build long suite

Xref #1793. There are many, many tests failing in the long suite. This issue covers fixing them (or removing sets of runs if we decide not to support them anymore) and getting the long suite clean so we can re-enable it.

```

Start by reproducing the debug-internal-32 and debug-internal-64 long-suite runs and grouping failures by the reported entry points in src/core/vmareas.c, src/core/fragment.c, and src/core/options.c. Check the listed suite tests and flaky cases to determine which failures need fixes versus removed runs. Done means the long suite is clean and can be re-enabled.
