Thanks, don't bother, I fixed it in master with the first attached patch.

Thanks.  I reproduced that problem.  It's an issue with the Emacs 
debugger, not with regular-expression matching.  (The regular expression 
matcher is very slow with your example -- which is a problem, but I 
suggest filing a separate bug report for the performance problem, as 
this bug report is about a SIGABRT.)

I fixed the problem in master by applying the second and third attached 
patches (which fix some related bugs while I was at it) and am marking 
this as done.  At least, it works for me; if it still doesn't work for 
you we can reopen the bug report.
