Summary0013600: Hash code calculation of TopLoc_Location is incorrect on 64-bit platforms
DescriptionIf number of transformations is bigger than 10, the next transformations are
not used for hash code generation (only on 64bit platforms): calculations are
performed on usigned long (64 bits), but returned value is Standard_Integer (32
bits).

Bug is reproduced on SALOME gluing operation (bug IPAL 13563).

It is proposed to put patch for this bug into the version 6.1.1.

Fix is attached.
Additional information
and documentation updates		Documentation remark, added by MPV 2006-10-19 07:43:10:

Improvements:
Hash code of the TopLoc_Location on 64bits-platforms now calculated better. This
fix have no effect on 32bits-platforms because the sizes on 'usigned long' and
'usigned int' variables are the same (4 bytes).
Modified entities:
TopLoc_Location.cxx method TopLoc_Location::HashCode - changed all local
variables type from 'unsigned long' to 'unsigned int'
TagsNo tags attached.
