-------------------------------------
Summary: bad_lexical_cast using TJSONProtocol
Key: THRIFT-1758
URL: https://issues.apache.org/jira/browse/THRIFT-1758
Project: Thrift
Issue Type: Bug
Components: C++ - Library
Affects Versions: 0.9
Environment: boost 1.52.0
iOS 6.0
iOS simulator 6.0
Reporter: Vitali Lovich
Priority: Critical
try{
std::string str("-0.003024283066062361")
double d = boost::lexical_cast<double>(str);
// bad_lexical_cast is thrown
} catch (const boost::bad_lexical_cast& e) {
std::cerr << e.what() << std::endl;
}
bad_lexical_cast is thrown. This is a problem for TJSONProtocol which relies
on lexical_cast handling this properly.
Looking through the code, it looks to have to do something with the
compile-time precision.
defining BOOST_LCAST_NO_COMPILE_TIME_PRECISION appears to resolve this issue
(although at the cost of performance).
this problem also doesn't appear to happen all the time with the same input
data. sometime's it's reproducible every time, other times it isn't.
