            Bug ID: 24974
           Summary: Debian Makefile lldb build is broken
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW

I've been looking into several issues with Sylvestre.

So far I see these:

1. the build is not producing a versioned lldb driver or liblldb.so, but the
non-versioned lldb driver is attempting to load the (not-present)
liblldb-3.8.so.

I manually created the link, which allows the lldb driver to load without
crashing.

Then I hit:

2. the python lldb module does not have the _lldb.so link in it.  This causes
all the tests that use the lldb module to fail.

I manually created the link, which allows the Python lldb module to load.  Then
I hit:

3. A segfault the first time a test runs:

# python /root/llvm-toolchain-snapshot-3.8~svn248678/tools/lldb/test/dotest.py
--executable
/root/llvm-toolchain-snapshot-3.8~svn248678/build-llvm/Release/bin/lldb -s
lldb-test-traces -u CXXFLAGS -u CFLAGS -C gcc-4.9 --no-multiprocess -v

['/root/llvm-toolchain-snapshot-3.8~svn248678/tools/lldb/test/dotest.py',
'--executable',
'/root/llvm-toolchain-snapshot-3.8~svn248678/build-llvm/Release/bin/lldb',
'-s', 'lldb-test-traces', '-u', 'CXXFLAGS', '-u', 'CFLAGS', '-C', 'gcc-4.9',
'--no-multiprocess', '-v']

LLDB import library dir:

lldb version 3.8.0 ( revision )
lldb.pre_flight: None

Session logs for test failures/errors/unexpected successes will go into
directory 'lldb-test-traces'
Command invoked:

lldb-test-traces -u CXXFLAGS -u CFLAGS -C gcc-4.9 --no-multiprocess -v
compilers=['gcc-4.9']

Configuration: arch=x86_64 compiler=gcc-4.9
----------------------------------------------------------------------
Collected 1386 tests

   1: test_display_source_python (TestSourceManager.SourceManagerTestCase)
      Test display of source using the SBSourceManager API. ... Segmentation
fault

That brings me to now.  I'll have a look at the seg fault.
