"CSS and JavaScript Cache" error

Permalink
After update to 8.1.0 while trying to create a new C5DK add-on blog entry or edit page:

RuntimeException
Unclosed regex pattern at position: 143509

https://xxxx/blog_post/create/255/255...
/concrete/vendor/tedivm/jshrink/src/JShrink/Minifier.php
line 525
if($this->a === "\n")
throw new \RuntimeException('Unclosed regex pattern at position: ' . $this->index);


This happens only when concrete5 cache CSS and JavaScript Cache is enabled.

No fix, and got a confirmation from the blog component author that this is a known issue.

For the time being what I do:
1. disable JS cache
2. edit blog
3. enable JS cache...
