Some malloc resulsts were not checked in standalone ncbuf code.
As this is debug/test code, we don't need to explicitly handle memory
errors, we just add some BUG_ON() to ensure that memory is properly
allocated and prevent unexpected results.
This partially fixes issue GH #2130.
No backport needed.
enum ncb_ret ret;
data0 = malloc(bufsize);
+ BUG_ON(!data0);
memset(data0, 0xff, bufsize);
bufarea = malloc(bufsize);
+ BUG_ON(!bufarea);
fprintf(stderr, "running unit tests\n");
