Bug #: 14281
Summary: boost::units::conversion_factor reaches UNREACHABLE
"Impossible TemplateArgument"
Product: clang
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
AssignedTo: unassignedclangbugs at nondot.org
ReportedBy: llvm+bugs at trds.de
CC: llvmbugs at cs.uiuc.edu
Classification: Unclassified
Triggering the bug:
#include <iostream>
#include <boost/units/systems/si/plane_angle.hpp>
#include <boost/units/systems/angle/gradians.hpp>
#include <boost/units/conversion.hpp>
int main(int argc, char **argv) {
using namespace boost::units;
std::cout << boost::units::conversion_factor(gradian::gradians,si::radians)
<< std::endl;
return 0;
}
The template stuff in Boost.Units is too heavy for me, I have no idea what the
problem could be. Message from clang was:
Impossible TemplateArgument
