OK, please lookup the detected C defines DBEGIN and PAGEWIDTH in
h/gclincl.h, and then figure out the value of page(p) according to
this macro definition:

((unsigned int)(((unsigned long)(((char *)(p))-DBEGIN)>>PAGEWIDTH)))


Please also do (at this point)

p heap_end
p holesize
p core_end

Take care,
