Bug ID: 48430
Summary: CallAndMessageChecker would infinite loop
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Static Analyzer
Assignee: dcough...@apple.com
Reporter: danny_sha...@outlook.com
CC: dcough...@apple.com, llvm-bugs@lists.llvm.org
Created attachment 24245
--> https://bugs.llvm.org/attachment.cgi?id=24245&action=edit
Preprocessed source file to reproduce the error.
The CallAndMessageChecker might get into infinite loop at
'generateVisitorsDiagnostics' function in 'BugReporter.cpp' due to a loop in
the errorNode graph.
I have attached a demo code that could reproduce this error. You could
reproduce the error by running clang static analyzer on the code with
'core.CallAndMessage' checker. I am unsure what causes errorNode graph to
contain a loop. Might be the function that passes right-value reference?
