“Too many root sets” when calling compile frequently

[Jean Abou Samra]

Hi,

Calling the Guile compiler often causes this BDWGC error: “Too
many root sets”.

scheme@(guile-user)> (define-syntax-rule (repeat n expr expr* ...) (do 
((i 0 (1+ i))) ((eqv? i n)) expr expr* ...))
scheme@(guile-user)> (use-modules (system base compile))
scheme@(guile-user)> (repeat 10000 (compile 5))
Too many root sets
Abandon (core dumped)

Any idea what is going on here? Should I report it as a bug?
Is there a workaround?

Thanks,
Jean
