Could be stress from your camera's winding motor, combined with
the relatively thin plastic base.  I've seen that phenomenon before.

XRG (and what looks like its successor XRS) is clearly listed
as a negative film in the Vuescan film types table:

Was XRG the predecessor of HDC?  It always seemed to me that
HDC was just Optima repackaged for consumer use, perhaps with 
less quality control, although Optima was not refrigerated
in the US distribution channel so it was hard to classify it 
as a true professional film.
