----------------------------------------
Summary: [Python binding] proton.float32('inf') and
proton.float32('-inf') fail during encoding on CentOS 7
Key: PROTON-1838
URL: https://issues.apache.org/jira/browse/PROTON-1838
Project: Qpid Proton
Issue Type: Bug
Components: python-binding
Reporter: Kim van der Riet
Attachments: simple_send.py
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:
{noformat}
[kvdr@rhm-x3550-05 ~]$ cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)
[kvdr@rhm-x3550-05 ~]$ python --version

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

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.
