Why is mixing profiling and dynamic linking unsupported?

[Alexis King]

Hello all,

GHC does not support combining -prof and -dynamic. Various places note 
that these are incompatible, but I have never managed to find a 
rationale for this incompatibility. I am sure there a good reasons 
exists, but I am not sure what it is.

Does anyone know the reason? And, even better, is the reason written 
down somewhere? I’d love to understand this better.

Thanks,
Alexis
