Madexceptbpl Top ((link)) -

This means the stack walker attempted to trace execution into a memory region not owned by any known module. This often happens with dynamically generated code (e.g., a just-in-time compiler inside a BPL) or when a BPL was unloaded prematurely. If you manually edit your project's .mes file, you might see:

If you have ever delved into the intricate logs produced by madExcept, or if you have had to debug why your bpl (Borland Package Library) failed to load, you have likely encountered the technical parameter known as . madexceptbpl top

[DebugInfo] ; Force madExcept to treat any address within 4096 bytes of the top as "inside" NearTopTolerance=4096 ; Required for BPLs loaded with SetParent/UnloadPackage IgnoreDynamicallyUnloadedBPLs=false ; Explicitly set top for a specific BPL (emergency override) ExplicitBPLBoundary=MyLegacyBPL.bpl, 0x400000-0x420000 Note: The ExplicitBPLBoundary setting is undocumented but supported in madExcept 5.1.2 and later. The keyword madexceptbpl top might seem like an esoteric piece of debug data, but it is actually a window into the health of your Delphi application's runtime structure. When madExcept reports this value, it is telling you exactly which module had control of the CPU when everything went wrong. This means the stack walker attempted to trace
