REGCOMP: repetition-o about wtbg2-mac HOT 2 OPEN

I have the same issue (with PacBio reads in my case).

from wtbg2-mac.

After tweaking the code so that it outputs the complete error message instead of just the first 13 characters, it turns out that the error message is -- REGCOMP: repetition-operator operand invalid --. This is actually due to the combination of the "lazy" operator ? with + (+?) being not POSIX-compliant, so it cannot be used on BSD/MacOS. As a quick fix I replaced +? with *, hence the regex became ^(.*)/[0-9]+_[0-9]+$ instead of ^(.+?)/[0-9]+_[0-9]+$. This is not exactly the same thing but it seems to be working now. However, for some reason I can only run wtdbg2 on MacOS with a single thread: as soon as I run wtdbg2 with more than one thread I get a malloc: double free for ptr 0x7fa938ec8800 error and the program crashes.
