I have a computer with 128 gigabytes of memory.
However, when I try to malloc memory, it only works if I malloc less than 64 gigabytes.
Is there some parameter I could change that would allow me to malloc more than 64 gigabytes.
Thanks,
Bernard Widynski

This has nothing to do with GCC. malloc is provided by the C library,
not by GCC.

malloc is not provided by GCC. Ask the developer of your libc.
