#168 trivial - malloc warning using gcc 8 on linux

[Ian Jeffray]

backend/reedsol.c: In function 'rs_init_gf':
backend/reedsol.c:81:20: warning: argument 1 value '4294967292' exceeds maximum object size 2147483647 [-Walloc-size-larger-than=]
alog = (int *) malloc(sizeof (int) * logmod);

Hi Ian,

I have added a small patch which should overcome this warning, although in practice rs_init_gf is never called with a value which would make this a problem. When you get the opportunity I would appreciate it if you could let me know if this satisfies gcc on your system.

Thanks,

Robin.

Hi Robin,

This does indeed fix the warning with GCC 8.2

Thanks,

Ian
