Re: [Cppcms-users] Advice on debugging file upload

[Artyom B. <art...@ya...>]

In order to get a trace the exception that is thrown should be derived from booster::runtime_error class.

CppDB is independent library that does not share the stack trace code with CppCMS, that
is why you can't get a backtrace from CppDB. It is not supported.

Also I'd recommend to use latest trunk, it has better support for backtracing
(not based on execinfo) that works on BSD and Mac OS X as well
