Not suer if the issue is within Fpc or clang...
Should this be reported against Fpc?
FPC defines the variables' debug info at the start of the function and
defines their lifetime as starting at the beginning of the function and
continuing until the end. But LLVM is free to modify these if it notices
these are too pessimistic
My guess is that even without optimisations, LLVM notices these
variables' values are not really used later on and reduces the
variables' live range.
