Address of stack memory associated with local variable returned to caller

Return pointer to function local data:
======================================
TQCommand::GetName and GetTitle
Both return local TString.Data()!

How to fix? (does it have to be thread safe?)

file: core/base/src/TQCommand.cxx:698:4 clang-analyzer-core.StackAddressEscape
error: Address of stack memory associated with local variable 'name' returned to caller
return name.Data();
