tested with nothing checked out on cyclone-bootstrap
used the (delay (force test case
eval.c:23791 lambda 19 - self_731184[1][0][2]
eval lambda 20 - k_73700
p ((closureN)((closureN)((closureN)k_73700 )->elts[0]))->elts[2]
(define (foldr func end lst)
lst is bad in debugger:
(gdb) p *((list)lst_73538 )
$56 = {hdr = {mark = 3221189204, grayed = 0 '\000'}, tag = -1073779712, cons_car = 0x8,
cons_cdr = 0xbffdf7f0}
this is lambda_706 in base.c
so... wtf?
(cdr exp) in wrapc seems corrupt - WTF?
(gdb) p *((list)((list)((closureN)self_731181)->elts[0])->cons_cdr)
$67 = {hdr = {mark = 3221189204, grayed = 0 '\000'}, tag = -1073779712, cons_car = 0x8,
cons_cdr = 0xbffdf7f0}
presumably the cdr is corrupt in eval-from-c as well? need to check that next
