I'm using a relatively large ctags file (~20 Mb) built for a C project I'm working on and I ran into the problem recently that the complete-symbol command (Ctrl-Alt-i) that auto-completes function and variable names in C files fails with the "stack overflow in regexp matcher" error.
Long story short, you need to increase the re_max_failures variable located in regex.c to fix this. Is this the right way? I don't know, but it works for me and the comments were not very clear to elaborate. There is also some "smart" logic related to re_max_failures in emacs.c that apparently tries to tweak it to the best value possible, but it turns out to be not smart enough for my use case.
