Flex itself uses a flex scanner. That scanner is running out of buffer
space when it tries to unput() the humongous macro you've defined. When
you remove the '/'s, you make it small enough so that it fits in the buffer;
removing spaces would do the same thing.
The fix is to either rethink how come you're using such a big macro and
perhaps there's another/better way to do it; or to rebuild flex's own
scan.c with a larger value for
#define YY_BUF_SIZE 16384
