Hello,

qi::int_parser works fine for a positive signed hex radix integer, but is failing for a negative signed hex radix integer.

I've got some sample code, it builds, but I am receiving a seg fault.

Oops, my mistake. An error in one of the rules. Fixed it, and can demonstrate that negative values do not seem to parse correctly: http://coliru.stacked-crooked.com/a/370b6aa5c167434b

...

My integer type is std::intmax_t, which on this platform I think is long long.

Is there an integer width constraint? And/or a signage problem?

Do I need to enable BOOST_HAS_LONG_LONG? Or is that enabled by default?

Cheers, thanks!
