Can you post your compiler version?

component property_tree → spirit

Never mind, could reproduce it. This appears to be a problem in Spirit.Classic. It crashes in boost::spirit::classic::impl::object_with_id_base_supply<unsigned long>::acquire ().

Reassigning.

Ok. Anyway, I used gcc 4.3.2 with glibc 2.7.

This is a known "classic" bug. The best course of action really is to switch to Spirit V2 which does not have these threading issues. Chances are very remote this will ever be fixed in "classic". A JSON parser is easy. It's about time to port to Spirit V2.

OK, taking the bug back then.

Hello,

I just hit this bug on boost 1.49.0 on a Raspbian system, and it looks like no progress was made on boost 1.50.0. Is there any milestone set for porting the parser to Spirit V2?

The JSON parser rewrite has landed on master, so this will be fixed in 1.59.
