[lldb-dev] lldb 340.4.119 unable to attach (El Capitan)

[Andre Vergison via lldb-dev]

Hi,
I tried Jason Molenda’s test code on El Capitan, lldb-340.4.119 (Jason Molenda via lldb-dev | 3 Oct 02:59 2015).
I’m connected to a remote VM using ssh.

tst$ echo 'int main () { }' > /tmp/a.c
tst$ xcrun clang /tmp/a.c -o /tmp/a.out
tst$ xcrun lldb /tmp/a.out
(lldb) target create "/tmp/a.out"
Current executable set to '/tmp/a.out' (x86_64).
(lldb) r
error: process exited with status -1 (unable to attach)
(lldb) run
error: process exited with status -1 (unable to attach)
(lldb) quit
tst$ ps -ef|grep a.out
  502 33174     1   0 12:20PM ttys000    0:00.00 /tmp/a.out
  502 33187     1   0 12:20PM ttys000    0:00.00 /tmp/a.out

I can’t even kill those using kill -9.

What’s going on here?

I tried the above because in fact I had a process which a segmentation fault 11, here’s what lldb makes out of the core dump:

txt$ lldb /cores/core.33158
(lldb) target create "/cores/core.33158"

 + filesize (0x31c57000) that extends beyond the end of the file (0x31c56000), t
he segment will be truncated to match

s section
Current executable set to '/cores/core.33158' (x86_64).
(lldb)

Is this related? Compiled with g++ :

tst$ g++ --version
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-inc
lude-dir=/usr/include/c++/4.2.1
Apple LLVM version 7.0.2 (clang-700.1.81)

Thx,
Andre
