Bug ID: 58232
Summary: False mudflap positive on std::setw
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libmudflap
Assignee: unassigned at gcc dot gnu.org
Reporter: andrey.vihrov at gmail dot com
Created attachment 30694
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30694&action=edit
Preprocessed source
Compiling and running the following code with "g++ -O2 -Wall -Wextra -fmudflap
-lmudflap" seems to produce a false mudflap violation positive:
#include <iostream>
#include <iomanip>
int main()
{
std::cout << std::setw(6);
}
Program output:
*******
mudflap violation 1 (check/read): time=1377279836.003018 ptr=0x7fec50b2cd00
