Description

Using the special float values 'inf' and '-inf' in a proton.float32 message body on CentOS 7 (both Python 2 and 3) result in the following error:

OverflowError: in method 'pn_data_put_float', argument 2 of type 'float'

and which can be observed by running the attached reproducer based on the simple_send.py example. The use of float special value 'NaN' does not produce this error, however.

This error does not occur on Fedora 27.
