Segmentation fault in ilc when building native code for System.Reflection.Tests (NativeAOT, ARM64, Ubuntu 18.04)

[Beau-Gosse-dev]

Notes

• This only seems to reproduce with the Release configuration, not Debug.
• This is just a targeted reproduction that was originally found when running this command from the repo root: ./build.sh clr.alljits+clr.tools+clr.nativeaotlibs+clr.nativeaotruntime+libs+libs.tests -rc Release -lc Release /p:TestNativeAot=true
• Originally found when trying to reproduce another issue: [NativeAOT] Enable Reflection library tests in Linux-ARM64 #70010

Reproduction Steps

1. On ARM64 Ubuntu 18.04
2. Make sure bin artifacts are cleared out to rebuild rm -rf /home/ubuntu/code/runtime/artifacts/bin/System.Reflection.Tests/
3. Make sure obj artifacts are cleared out to rebuild rm -rf /home/ubuntu/code/runtime/artifacts/obj/System.Reflection.Tests/
4. Navigate to reflection tests cd ~/code/runtime/src/libraries/System.Reflection/tests
5. Run tests for NativeAOT ../../../../dotnet.sh build /t:Test /p:TestNativeAot=true -c Release -v d

Debugging Steps (after running Reproduction Steps):

1. Setup symbols for debugging cp /home/ubuntu/code/runtime/artifacts/bin/coreclr/Linux.arm64.Release/*.dbg /home/ubuntu/code/runtime/artifacts/bin/coreclr/Linux.arm64.Release/ilc
2. Point gdb to ilc gdb /home/ubuntu/code/runtime/artifacts/bin/coreclr/Linux.arm64.Release/ilc/ilc
3. Tell gdb where symbols are set debug-file-directory /home/ubuntu/code/runtime/artifacts/bin/coreclr/Linux.arm64.Release/ilc
4. Run against reflection tests r @"/home/ubuntu/code/runtime/artifacts/obj/System.Reflection.Tests/Release/net7.0/native/System.Reflection.Tests.ilc.rsp"

[jkotas]

Could you please get a stacktrace of the crash with symbols? You may need to tell the gdb to load the symbols from /home/ubuntu/code/runtime/artifacts/bin/coreclr/Linux.arm64.Release, or copy the *.dbg files from /home/ubuntu/code/runtime/artifacts/bin/coreclr/Linux.arm64.Release to /home/ubuntu/code/runtime/artifacts/bin/coreclr/Linux.arm64.Release/ilc.

[Beau-Gosse-dev]

Thanks, @jkotas I was wondering how to get the symbols. I've updated the original issue with the symbol filled bt.

When running in gdb, I did see warning: the debug information found in "/home/ubuntu/code/runtime/artifacts/bin/coreclr/Linux.arm64.Release/ilc/libclrjit.so.dbg" does not match "/home/ubuntu/code/runtime/artifacts/bin/coreclr/Linux.arm64.Release/ilc/libclrjit.so" (CRC mismatch).

Is that actually an issue?
