Subject: [PATCH] Increase the size for the demangled symbol buffer to 8192
 bytes

Previously the 1024 bytes was potentially too small for some complex
rust symbols leading to failures in demangling.

Bumping this to 8x should reduce the chances for this, but still
gives off a strong "640K Ought to be Enough for Anyone" vibe :)
