It's unlikely this is right. This symbol is the code for the function
GHC.Base.$s$dmin, which is a specialised version ($s) of the default method ($d)
for min, in class Ord. I very much doubt that min calls malloc()!
So it probably means that there are some symbols missing in your program binary.
Try asking gdb what lies at that address, maybe?
