Replacetext taking forever under 8.1.7

I am trying to port a stack that runs fine under Livecode 7.1.4 to Livecode 8.1.7 in order to take advantage of 8.1.7’s 64-bit standalone app capability for Mac OS X “High Sierra". That is when I found that under either Yosemite or High Sierra a “replacetext" action takes over 20 minutes under 8.1.7 while under 7.1.4 it takes less than one second! The replacetext is to remove extra spaces in a 60,000 line (1.9 million character) variable, and looks like this:

put replacetext(holdIt1,"[ ]{2,10}",empty) into holdIt 

Under 8.1.7 I get the dreaded spinning beachball, although the replacetext action eventually finishes (after 20 minutes), and the script then runs to completion.

Any ideas about causes and cures for this issue?
