Trouble with loading struct in 2014b

I have a .mat file that has only a struct variable in it, created with 2014a. When I try to load it in 2014b, it crashes with error: Assertion in void __cdecl `anonymous-namespace'::mwJavaAbort(void) at b:\matlab\src\jmi\javainit.cpp line 1319:Fatal Java Exception.

I can load the file without problems in 2014a. I also can load structs in 2014b that are saved with 2014b. So there seems to be backwards incompatibility. Anybody has a similar problem/ solution?

Is there anything special in the struct that is no longer valid in R2014b?

Can you attach the file so we can try it?
