[Lldb-commits] [PATCH] D71297: Remove unsound caching in LanguageCategory

[Adrian Prantl via Phabricator via lldb-commits]

aprantl created this revision.
aprantl added reviewers: jingham, davide.
aprantl added a parent revision: D71296: Replace redundant code in 
LanguageCategory with templates (NFC).
Analogous to https://reviews.llvm.org/D71233 it is not safe to cache something 
that depends on the actual ValueObject in a cache then keys only off the type 
name.
