Ok. Still, there can be problems in holding non-floating values in floating
point parameters, because not all bits are necessarily preserved (e.g. padding
bits inside of the floating point format).

IPA-split puts the double access to the union in the .part function
and keeps only the long int access in the "original" function.
IPA-SRA thinks it can work with that but the code in "transitive" call
