#6036 closed Bugs (fixed)

incorrect rethrow in member function void mapped_file_impl::map_file(param_type& p)

Reported by: Valentin Batz <valentin.b@…> Owned by: Daniel James
Milestone: Boost 1.55.0 Component: iostreams
Version: Boost 1.47.0 Severity: Problem
Keywords: Cc:

Description

The rethrow with boost::throw_exception(e) involves 'object slicing' by making a copy of the base-class object. The original exception-information will be lost. To re-throw the current exception you have to throw without any argument.

(In [84942]) Rethrow exception without slicing. Fixes #6036.

Maybe it should use catch(...), that's what iostreams uses everywhere else.
