Hi all.

F# is giving me a mysterious warning. Say I'm writing a DLL containing the following type:

type Foo<'a>() =
member f.array_of_a : 'a[] = Array.zero_create 100
member f.array_of_a_2 : 'a[] = f.array_of_a

If I compile the DLL as a debug build, I get no warning. However, if I compile it as a release build, F# complains:

warning FS0191: ptypar_spec: typar is not rigid.

The following types produce no warnings:

type Foo2<'a>() =
member f.array_of_a : 'a[] = Array.zero_create 100

type Foo3<'a>() =
member f.array_of_a : 'a[] = Array.zero_create 100
member f.array_of_a_2 : 'a[] = Array.zero_create 100

Any idea what this warning means? Is it anything to be concerned about?

Thanks!
