Overview:
The static analyzer gives me an illegal instruction crash when processing some
fairly simple C++ code.
Steps to reproduce:
Analyze this code:
-------------------------
#include <string>
bool IsFloating();
bool IsHidden( const std::string& inName );
static void Foo( const char* inName,
long inFlags )
{
bool isIgnored =
IsFloating() ||
IsFloating() ||
(
IsFloating()
&& ((inFlags & 4) != 0)
)
|| IsHidden( inName )
;
}
-------------------------
Actual results:
Illegal instruction crash. Backtrace attached.
Build date:
clang version 3.4 (trunk 186710)
Target: x86_64-apple-darwin11.4.2
Thread model: posix</pre>
