Stack trace shows: __libc_free -> box64/free -> sourcepawn.jit.x86.so Workaround attempted: BOX64_DYNAREC=0, BOX64_MALLOC_HACK=2, LD_PRELOAD jemalloc — none worked. Is there a way to make Box32 handle mmap-allocated memory correctly when freed via free()? Additional context: - The server was installed using DepotDownloader (not SteamCMD), so there is no ~/.steam/steambeta/ - Box64 + Box32 is used directly with srcds_run. - MetaMod (1.12 i486) and SourceMod (1.11 i486) load correctly up to the point of initializing sourcepawn.jit.x86.so. - The crash happens right after "Using emulated .../sourcepawn.jit.x86.so" when attempting to load the first plugin (.smx). - Also tested with SourceMod 1.10 and 1.11, same result. - Without SourceMod, the server runs perfectly stable (pure Box32, no JIT). Additional question: is there a SourceMod build compiled natively for ARM64/aarch64 that would avoid going through 32-bit emulation entirely? That would be the ideal solution if Box32 can't be fixed short-term.

El stack trace muestra: __libc_free -> box64/free -> sourcepawn.jit.x86.so Intenté: BOX64_DYNAREC=0, BOX64_MALLOC_HACK=2, LD_PRELOAD con jemalloc — ninguno funcionó. ¿Hay alguna forma de hacer que Box32 maneje correctamente la memoria alocada con mmap cuando se libera con free()? Contexto adicional: - El servidor fue instalado con DepotDownloader (no SteamCMD), por lo que no existe ~/.steam/steambeta/ - solo se usa Box64 + Box32 directamente con srcds_run. - MetaMod (1.12 i486) y SourceMod (1.11 i486) cargan correctamente hasta el punto de inicializar sourcepawn.jit.x86.so. - El crash ocurre justo después de "Using emulated .../sourcepawn.jit.x86.so" al intentar cargar el primer plugin (.smx). - Probé también con SourceMod 1.10 y 1.11, mismo resultado. - Sin SourceMod, el servidor corre perfectamente estable (Box32 puro, sin JIT). Pregunta adicional: ¿existe alguna build de SourceMod compilada nativamente para ARM64/aarch64 que evite pasar por la emulación 32-bit por completo? Eso sería la solución ideal si Box32 no puede resolverse a corto plazo.
