in debug mode, incorrect handling of quasiquoted expressions #270

Open hyln9 opened 10 years ago

hyln9 commented 10 years ago

Running the program below as:

$ ikarus --r6rs-script hurtme.sps ciao

while in debug mode:

$ ikarus --debug --r6rs-script hurtme.sps ciao ciao

(import (rnrs)) (define (b) (display "ciao\n")) (quasiquote (,(b)))

notice that changing the expression to "(quasiquote ,(b))" does not exercise the bug.

Matched by Vicare issue #3, fixed in "ikarus" branch's head by artificially setting optimisation level to zero.

P.S. It happens only when the optimisation level is not zero.
