We noticed a weird problem when testing the pharo exercism project.

When loading on Windows10 in a fresh 64bit image with the following evaluate in 
the playground:

Metacello new 
 baseline: 'Exercism'; 
 repository: 'github://exercism/pharo-smalltalk:master/dev/src';
 load.

The project seemed to load correctly (but we seemed to hit an issue with an 
http submit giving a 404 error - which weirdly works in 32bit and OSX 64/32). 
Anyway - the real question here is that when trying to reproduce this in a 
second fresh 64bit image 2 users now have reported getting the long filename 
error:

LGit_GIT_EEXISTS: Failed to stat file 
'C:/Users/sam/Documents/Pharo/images/exercism-test-run-7.0-32...stance/testRaiseUnexpectedMessageWhenTooMuchMessages.st':
 The filename or extension is too long.

And the second user got the same but with a different filename: 
ruleRBUtlitiesMethodsRuleV1FalsePositve.st

I know there is a long standing problem with Windows and file path lengths - 
but why would it work the first time and then subsequently fail in fresh 
installs? Is something being cached on windows that isn’t on other platforms? 
(Writing this - I’m wondering if there is that shared pharo Iceberg setting for 
Share repos that might be implicated?)

Also - given Exercism is in Tonel format and those files aren’t in exercism, 
and in fact I’m struggling to find where they are defined (my images don’t have 
them) - there is something very weird going on.

I wonder if we have another error that is masking all of this?

Ultimately my question is - where is the Pharo issue that is tracking this 
problem? I’ve seen it mentioned lots of times here, but can’t see anything in 
the issues that I can tack the above onto?

For reference - our exercism issue is:
