axsk commented 8 years ago

I am getting a similar ERROR: TypeError: getfield: expected Symbol, got Int64 when trying to save a value of composite type, including anonymous function, which I expect to pose the problem in my case (as I experienced problems with them and JLD all along).

timholy commented 8 years ago

For the top case, I don't get the reported error, instead I get ERROR: cannot write a pointer to JLD file. This turns out to be because backtraces now return StackFrame which includes Nullable{LambdaInfo} and LambdaInfo.fptr is of type Ptr{Void}. So someone is going to have to create writeas/readas methods for StackFrame, but of course this will result in the fptr effectively being thrown away.

@axsk, your case doesn't include enough detail to replicate. But anonymous functions are extremely problematic overall, and at the moment it doesn't seem that anyone has a clear path for them going forward with julia-0.5.

I got this error while saving macroexpanded code that contains module. Eg. JLD.save("temp.jld", "somemodule", Base) triggers it. A nice error message would make it easier to spot the problem.
