Bug ID: 32921
Summary: Undefined variables in class Status in
VirtualFileSystem.h
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: -New Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: zec...@gmail.com
CC: llvm-bugs@lists.llvm.org
After compiling clang trunk 301516 with gnu gcc -fsanitize=undefined option
I got many warnings at run time concerning undefined variables.
Many of them at tools/clang/include/clang/Basic/VirtualFileSystem.h:62
"Status() : Type(llvm::sys::fs::file_type::status_error) {}"
that I suggest to change into
"Status() : Type(llvm::sys::fs::file_type::status_error)
{Perms=llvm::sys::fs::no_perms;IsVFSMapped=false;}"
Thus explicitely initializing two local variables to safe values
and avoiding sanitizer warnings.
I propose to put this change in the trunk version.
