I looked more thoroughly at print.c code, and found that in the print
routine, when print_preprocess has been called, with the above change
it can leave print_depth incremented, which leads to the "Apparently
circular structure being printed" error in next call to print_object.
With the following patch, that resets print_depth to 0 before to call
print_object, the byte-compiler no more fails to print large byte code
data.
WDYT?

* print.c (print): Reset print_depth before to call print_object.
