I'm having this issue on php 7.2.

Gonna mark this as fixed, ping me if 150 is too short so I can look into it, thanks!

Please try using this snapshot:

For Windows:

I just committed a fix for adding support for Panasonic formats, which involved increasing this
limit to 150, can you confirm this still works with that, or do you need it to be 200 for the
Fujifilm format to work?

I don't know why a fix is not included, it seems to be a very straightforward change with no
side-effects.

I have been applying the fix I described originally every time I upgrade php and it works very well.
