[Lldb-commits] [PATCH] Fix StdVBoolImplementation to handle large vectors

[Tamas Berghammer]

Hi sivachandra,

Fix StdVBoolImplementation to handle large vectors

The previous implementation only read out the first element of the underlying storage array. Because of it only the first 32 (on x86) or the first 64 (on x86_64) element was displayed.
