AbstractSourceFileDepGraphFactory-8a18b3.zip

[shafik]

May be related to: #49051

[Endilll]

I can't reproduce this using either Clang 17 with assertions or debug build of trunk d2c2fa9 (Sep 13). Maybe a newer trunk is required, but I can't test it at the moment.

[bc-lee]

See the same issue #68524 and my PR #68525.

[Endilll]

I built Clang at the exact commit mentioned in the reproducer script, and it works for me.
Can you confirm this issue on latest release or trunk?

[dhoepfl]

I haven’t been able to compile swiftc in several month.

I think this is fixed by #78716
