Bug description
When I create and launch a new image of the latest stable Pharo version 10.0 a debugger opens.

To Reproduce
Steps to reproduce the behavior:

1. Download the latest PharoLauncher PharoLauncher-3.0.1-x64.dmg
2. Create a new image from the latest stable template Pharo 10.0 - 64bit (stable)
3. Click Launch
4. The image starts and a debugger appears.

Expected behavior
The debugger should not appear.

Version information:

• OS: macOS
• Version: 12.5 (21G72)
• Pharo Version Pharo 10.0 - 64bit (stable)

Expected development cost
No idea about that. I am of course willing to test a fix.

Hitting this as well. Mac OS ARM64.
Only hitting this with Pharo10 build 523. When I revert to Pharo10 build 522, everything works fine.

It's not just a debugger appearing on opening, it also fails when trying to execute a Metacello load, such as:

Metacello new
 baseline:'Seaside3';
 repository: 'github://SeasideSt/Seaside:master/repository';
 load:'CI'.

I am also running into this problem. I tracked the problem to LGitLibrary>>#macLibraryName. The array contains two set of quotes around the first entry. This causes the entry to be interpreted in an interesting manner. Instead of a single entry, it is viewed as 9 separate array entries (as though it were a dynamic array.)

When FFIMacLibraryFinder concatenates the empty String to a FileReference, it ends up returning the FileSystem Root. This exists, FFIMacLibraryFinder incorrect determines the name of the library to be '/' and the FFI calls fail.

Updating #macLibraryName 'resolves' the bad behavior. There seem to be a few issues at play in this issue.

1. #macLibraryName is incorrectly implemented
2. AbstractFileReference>>#/ returns the root when passed an empty string argument
3. Arrays created using #{) are treated like dynamic arrays in some circumstances -- I don't think this is all that problematic

I don't know where to submit a patch for #macLibraryName. I can't seem to find the right repo. I did notice that Feenk has patched this method.

Hi!

There are the PRs #11581 and #11582 dealing with this problem for Pharo10 and Pharo9. Pharo11 should be fixed in the next build.

A student in my course with Moose this semester is hitting this bug (there's no Moose Suite for Pharo 11 as far as I know). Did Pharo 10 get this fix? Maybe the "Moose Suite 10 (development)" image is not using it?
