IMPALA-5031: signed overflow is undefined behavior
Tis patch fixes a signed overflow in the test
StringToDecimal.LargeDecimals. The interesting part of the backtrace
is:
util/string-parser.h:397:14: runtime error: signed integer overflow:
0x4b3b4ca85a86c47a098a223fffffffff * 10 cannot be represented in
type '__int128'
#0 void StringParser::ApplyExponent<__int128>(int, int,
signed char, __int128*, int*, int*) util/string-parser.h:397:14
#1 DecimalValue<__int128> StringParser::StringToDecimal<__int128>
(char const*, int, int, int, bool, StringParser::ParseResult*)
util/string-parser.h:221:5
#2 void VerifyParse<__int128>(string const&, int, int, bool,
DecimalValue<__int128> const&, StringParser::ParseResult)
runtime/decimal-test.cc:53:25
#3 void VerifyParse<__int128>(string const&, int, int,
DecimalValue<__int128> const&, StringParser::ParseResult)
