Compiler#new_program
instantiates a newProgram
instance which is used for compiling a macrorun
program. Some properties (such as codegen target) can be shared between multiple compilations. But theTargetMachine
instance must not be shared because this would leak potentially incompatible data layouts between programs.This patch creates a new instance of
TargetMachine
for every program.See #14496 (comment) and previous comments for details.
Resolves (probably) #14496
