Description

Expected behavior:
When you use pn_message_save* functions API, you pass char *data and size_t *size. If the size IS NOT enough to save mesage body text, this functions return in size_t *size variable, the necessary buffer size and return PN_OVERFLOW status.

Behavior observed:
The pn_message_save* functions API return PN_OVERFLOW status and DO NOT return a correct value of necessary buffer.

Patch to fix expected behavior is attached:
