Re: [Chicken-users] Declare large expressions as read-only and not gc-able?

[Jim Ursetto]

I'll bet if you define a 100MB literal, the resulting C file would be at least 
a gigabyte and neither CHICKEN nor gcc would be able to handle it.  You could 
try it and let us know.

You could evict it theoretically, but for something that big, you may have to 
create your own data structure in C and malloc it.

I'm curious what this expression is for.
