Bug In VM?: SIGSEGV: Illegal storage access. (Attempt to read from nil?)

[loloicci]

Sometimes SIGSEGV: Illegal storage access. (Attempt to read from nil?) is issued in compile-time.
Maybe it is bug in VM (and not in nimly).

maybe sets.incl has some bugs with VM.

nimly: 3ca678e22da3fc0607be3a4a875f77859e5f8524
Nim: fabc2a7086bb83afc2abfd6d5841f25c8387609f

Sometimes following error is issued when nimy is used.

Maybe fixed in Nim v1.0.0.
