Bug ID: 19161
Summary: Analyzer does not realise list is not empty
Product: clang
Version: 3.3
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: enhancement
Priority: P
Component: Static Analyzer
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
The analyzer (in Xcode 5.1) reports a "Use of memory after it is freed" if you
test for !empty and then access a list. Perhaps I'm missing something, or
maybe this is just too hard for the analyser?
#include <list>
struct QueueEntry {
bool writer;
};
static std::list<QueueEntry> i_actionQueue;
int main(int argc, const char * argv[])
{
while ( !i_actionQueue.empty() && i_actionQueue.begin()->writer ) {
i_actionQueue.pop_front();
}
return 0;
}
