It might be a compile order issue. I use COMPILE_OPT IDL2 in nearly
everything (which includes STRICTARR as David mentioned), so it is
rarely a problem for me, but if this is not for you try compiling the
second embedded function before the first when creating your save
file. That will usually fix it.
