Create_Context crashes on windows since GNAT native 12.1.2

Dear Libadalang developers,

Recently, GNAT native 12.1.2 was released in the Alire ecosystem.
Unfortunately, this resulted in crashes in all my crates on the windows platform.

I have been able to pinpoint the problem in the attached reproducer.
bug_native12.zip

When typing
alr run
I would expect the output

Start
Done

However, as you will see one gets

Start

Could you please fix the bug?
Furthermore, could you release a new version of libadalang for the Alire ecosystem that works with GNAT native 12.1.2?

Thanks in advance,

Pierre van de Laar

Hi Pierre,

Thank you for the report. We'll have a look.

I have been able to pinpoint it a little more precise:
Libadalang.Internal_Default_Provider.Create

Still don't understand what causes the problem...
Have even experienced it on GNAT 11.2.4 - unclear whether installing 12.1.2 is already enough to trigger the bug
or it is a improvement of windows.

I still have a lot of problems due to this bug.
I have been able to pinpoint it even further: gnatcoll-projects.adb calls Non_Blocking_Spawn (in GNAT.EXPECT [g-expect.adb])
on line 8307 with
C:\Users\laarpjljvd\.config\alire\cache\dependencies\gnat_native_11.2.4_2f9c5d6d\bin\gnatls.exe
that fails.

Which is really strange since

PS C:\path\to\bug_native12> alr printenv --powershell | Invoke-Expression
PS C:\path\to\bug_native12> C:\Users\laarpjljvd\.config\alire\cache\dependencies\gnat_native_11.2.4_2f9c5d6d\bin\gnatls.exe -v

nicely yields
