Bug ID: 22450
Summary: clang Parser assertion failure due to typo of sizeof
keyword
Product: clang
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangbugs at nondot.org
Reporter: mukai at chromium.org
CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
Classification: Unclassified
Created attachment 13801
--> http://llvm.org/bugs/attachment.cgi?id=13801&action=edit
the reproduced c++ file.
% clang++ --version
clang version 3.6.0 (trunk 223108)
Target: x86_64-unknown-linux-gnu
Thread model: posix
The attached file causes a crash of clang++ due to assertion failed.
I've met on my (typo-ed) file but a minimum reproducible file is:
int main(void) {
return test(sizeo);
}
command-log:
% clang++ foo.cc
foo.cc:2:15: error: use of undeclared identifier 'sizeo'; did you mean
'sizeof'?
return test(sizeo);
