You need to look for the actual error that causes this.
Is there are relevant message in *Messages*?
Maybe M-x jit-lock-debug-mode RET (along with enabling the debugger)
could help as well.

The limits would be in src/regexp.c
BTW, instead of creating a monster regexp, maybe another approach is to
use a simple regexp that matches any identifier in function position
and then look up a table to see what kind of highlighting to apply to it
(IIRC that's what we do in elisp-mode to highlight macro calls
differently from function calls).
