            Bug ID: 44155
           Summary: LLDB doesn't preserve values of strings
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: All Bugs
          Assignee: lldb-dev at lists.llvm.org
          Reporter: teemperor at gmail.com
                CC: jdevlieghere at apple.com, llvm-bugs at lists.llvm.org

(lldb) expr "foo"
(const char [4]) $0 = "foo"
(lldb) expr "bar"
(const char [4]) $1 = "bar"
(lldb) expr $0
(const char [4]) $0 = “bar”
^ Should have printed "foo"

This however works just fine:

(lldb) expr char c[] = "foo"; c
(char [4]) $0 = "foo"
(lldb) expr char c[] = "bar"; c
(char [4]) $1 = "bar"
(lldb) expr $0
(char [4]) $0 = “foo”

We either need to keep the sections for the strings around or support copying
the related memory to our storage for persistent variable values.
