Summary: lit.py fails when running all tests on Win7 x64 with
Visual Studio 2008
Product: clang
Version: trunk
Platform: PC
OS/Version: other
Status: NEW
Severity: normal
Priority: P
Component: Driver
AssignedTo: unassignedclangbugs at nondot.org
ReportedBy: johnw at boostpro.com
CC: llvmbugs at cs.uiuc.edu
Here at BoostPro we run several automated tests of Clang, using OS X and
Windows 7, with both Visual Studio 2008 and 2010.
Lately we've seen a lot of failures that we are unable to reproduce either in
the debugger, by running clang.exe, or by running lit.py directly for the
given test. It only fails if we run the full suite.
At the end of the message is an example of such a failure. This exact same
stack occurs for 0-5 different tests, with that number fluctuating on a daily
basis (though usually from the same candidate set).
What's *very* odd about all this is that if I manually set a specific PATH in
TestRunner.py, I can then get the test to fail when running lit.py for that
specific test. Here is what I insert, at line 163, just before the call to
"procs.append(subprocess.Popen":

With this PATH, the test always fails and produces the same stack trace. If I
remove *any* of these paths, or reduce the length of any of them by _even one
character_, the test passes. If blank out the PATH, the test passes. But if
I add _any_ characters to any of the pathnames, it still fails.
