Exception unwinding broken with Xcode 15 linker #92297
Description
Recently I've started observing a strange behavior when attempting to run tests where first chance exceptions seem to be crashing the test runner.
For example, running: ./dotnet.sh test src/libraries/System.Formats.Cbor/tests
Produces:
The active test run was aborted. Reason: Test host process crashed : Unhandled exception. System.Formats.Cbor.CborContentException: The current CBOR map contains an incomplete key/value pair.
at System.Formats.Cbor.CborReader.PeekStateCore() in /Users/vcsjones/Projects/runtime/src/libraries/System.Formats.Cbor/src/System/Formats/Cbor/Reader/CborReader.PeekState.cs:line 82
at System.Formats.Cbor.CborReader.SkipNextNode(Int32& depth) in /Users/vcsjones/Projects/runtime/src/libraries/System.Formats.Cbor/src/System/Formats/Cbor/Reader/CborReader.SkipValue.cs:line 70
at System.Formats.Cbor.CborReader.SkipToAncestor(Int32 depth, Boolean disableConformanceModeChecks) in /Users/vcsjones/Projects/runtime/src/libraries/System.Formats.Cbor/src/System/Formats/Cbor/Reader/CborReader.SkipValue.cs:line 51
I don't see any reason this exception should crash the test runner.
It's not just in S.F.Cbor. For Tar:
Skipped System.Formats.Tar.Tests.TarWriter_WriteEntry_File_Tests.CreateEntryFromFileOwnedByNonExistentUser [1 ms]
The active test run was aborted. Reason: Test host process crashed : Unhandled exception. Unhandled exception. System.IO.IOException: The file '/var/folders/gc/qfr6cnsj3p1fc1944dkn1t6h0000gn/T/33hxgrfd.1wv/file.tar' already exists.

I have my suspicion that the issue is due to upgrade Xcode to Xcode 15 (However I am on macOS 13 still).
Currently, I can't run any tests.
