"""

|
|
Test that LLDB can launch a linux executable through the dynamic loader where
|
||
|
|
the main executable has an extra exported "_r_debug" symbol that used to mess
|
||
|
|
up shared library loading with DYLDRendezvous and the POSIX dynamic loader
|
||
|
|
plug-in. What used to happen is that any shared libraries other than the main
|
||
|
|
executable and the dynamic loader and VSDO would not get loaded. This test
|
||
|
|
checks to make sure that we still load libraries correctly when we have
|
||
|
|
multiple "_r_debug" symbols. See comments in the main.cpp source file for full
|
||
|
|
details on what the problem is.
