<br>
I installed a 32-bit Windows build of LLVM 4.0.0 from this page:<br>
<br>
<a href="http://llvm.org/builds/" rel="noreferrer" target="_blank">http://llvm.org/builds/</a><br>
<br>
where it is identified as "based on SVN r284979 (24 October 2016)".<br>
(I actually wanted only LLDB, but there doesn't seem to be a separate<br>
installer for that.) The machine where I installed it runs the 64-bit<br>
Windows 7 OS. The only setting I changed during the installation was<br>
the installation directory: instead of the default under "C:\Program<br>
Files (x86)" I've installed it under d:\usr.<br>
<br>
The installation went fine. After installing, I found that I needed<br>
Python 3.5.x, so I installed this:<br>
<br>
<a href="https://www.python.org/ftp/python/3.5.2/python-3.5.2.exe" rel="noreferrer" target="_blank">https://www.python.org/ftp/<wbr>python/3.5.2/python-3.5.2.exe</a><br>
<br>
The installed Python works correctly.<br>
<br>
After all this, lldb crashes when it attempts to start a debuggee.<br>
Specifically, whenever I say "process launch -s" inside the debugger,<br>
it crashes. (The information about the crash available in the Windows<br>
Event Viewer is at the end of this message.) The same happens if I<br>
type "lldb PROGRAM" from the Windows cmd.exe prompt. Until I try to<br>
launch the debuggee, lldb works: I can type the various commands,<br>
including "help" and they produce expected results.<br>
<br>
The crash is inside liblldb.dll, and the exception code seems to<br>
indicate that some C runtime library function is called with incorrect<br>
or invalid arguments.<br>
<br>
Other programs that came with the installation -- clang, llvm-ar,<br>
llvm-objdump -- seem to work fine and produce the expected results.<br>
In particular, I compiled a small C program with clang.<br>
<br>
So the installation seems to work fine, and only lldb crashes.<br>
<br>
What am I doing wrong?<br>
<br>
Thanks in advance for any help.<br>
<br>
