Re: Putting an all-zero variable into BSS

Putting readonly data into .rodata isn't required by the C standard I think

size limit.


That would be the best solution, I think.


IIRC GCC behaved one or another way in the past already
and the last change might be due to security concerns.


I cannot speak to that. If there is concern for C, we could also
limit this to Fortran.


Btw, large
all-zeros constant objects don't make very much sense...


I am well aware of this, but we're not going to change this
before the GCC 9 release :-)

So, would it be possible for you to make the change wrt .bss?
I would not have the first idea where to start looking.
