Putting readonly data into .rodata isn't required by the C standard I think so we could freely choose .bss for data exceeding a reasonable size limit. IIRC GCC behaved one or another way in the past already and the last change might be due to security concerns. Btw, large all-zeros constant objects don't make very much sense... Richard.
