tar file containing test directory
If I try to attach to a gdbserver with lldb on Ubuntu 12.04 or Ubuntu 13.10,
lldb attaches to the process, successfully stops the program, but is unable to
display the stack or dump the registers:
(lldb) bt
* thread #1: tid = 7330, , stop reason = signal SIGTRAP
* frame #0:
(lldb) register read
error: invalid frame
(lldb)
The commands I'm using to connect to the gdbserver are:
platform select remote-linux
target create --arch x86_64--linux-gnu ./foo
gdb-remote localhost:2388
Trying without the "platform select" line gives the same results, as does
removing the --arch x86_64--linux-gnu
A test directory is attached to this bug report. In that test directory, run
the following, *each in its own shell window* :
- make run # will run executable, which has an infinite loop of sleep(1)
- make gdbserver # will bring up gdbserver, attaching to the executable
- lldb # will execute commands in .lldbinit, attaching to gdbserver</pre>
