I can tell you why the problem is likely occuring but not how to fix it :-(

mrd_struct.pro creates a structure given a list of tag names and associated variables inside a program ( http://idlastro.gsfc.nasa.gov/ftp/pro/structure/mrd_struct.p ro ). By default, it uses EXECUTE() but it also has a less capable mode which does not use EXECUTE() and so can be used with the viriual machine. In this less capable mode, one supplies mrd_struct with the data type and dimensions of the variables rather than the variables themselves. I suspect FITSHEAD2STRUCT needs to be modified -- in a manner similar to mrdfits.pro -- so it can call mrd_struct in this less capable mode.
