            Bug ID: 16443
           Summary: target create doesn't expand ~ on Linux
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs

    Classification: Unclassified

If you start lldb and do a target create on a path with a ~ as part of the
path, it is accepted but when trying to run the process the launch fails.

Here's an example where the test binary is ~/a.out  it is also
/home/matthews/a.out which works fine.  Both paths work fine when used on the
command line (most likely due to shell expansion)

matthews at matthews-linux:~/work/llvm/llvm/build$ bin/lldb
(lldb) version
lldb version 3.4 ( http://llvm.org/svn/llvm-project/lldb/trunk revision 184861)
(lldb) target create ~/a.out
Current executable set to '~/a.out' (x86_64).
(lldb) run
error: process launch failed: Child exec failed.

(lldb) target create /home/matthews/a.out
Current executable set to '/home/matthews/a.out' (x86_64).
(lldb) run
Process 4493 launched: '/home/matthews/a.out' (x86_64)
Hello world!
Function 106
Process 4493 exited with status = 13 (0x0000000d) 

The target list command shows the full path to the file, but that full path
isn't being used when the process is started with run.

(lldb) target create ~/a.out
Current executable set to '~/a.out' (x86_64).
(lldb) target list
Current targets:
* target #0: /home/matthews/a.out ( arch=x86_64--linux, platform=localhost )
