Summary0023365: Name collision of global IsEqual() leads to overriding user's definition
DescriptionAIS_ConnectedShape.cxx defines a global IsEqual() function, which in run-time overrides user's definition of IsEqual() in completely different module.

This is Linux-specific behavior caused by global resolution. It is unclear why static symbol gets exported and redefines another symbol though.

See details on the forum - http://www.opencascade.org/org/forum/thread_23553/?forum=3.
Additional information
and documentation updates		Recommendation to use NCollection containers is to use a hasher parameter (introduced in 6.5.3) instead of global definition of IsEqual()/HashCode(), and also use of explicit namespaces' to avoid name collision.
TagsNo tags attached.
