csc.exe x86 fails with "error Out of memory."

[nietras]

After updating to .NET SDK 10.0.103 we see problems on a specific CI machine, with csc.exe for x86 .NET crashing as part of compiling a WPF app. Specifically, on a temp WPF project. With an error like:

WpfApp_z5p04kao_wpftmp net10.0-windows failed with 1 error(s) (3.0s)
    D:\agent\_work\_tool\dotnet(x86)\sdk\10.0.103\Roslyn\Microsoft.CSharp.Core.targets(84,5): error Out of memory.  

We run this as part of x86 (32-bit) testing.

If you could capture a binlog and a complog or a crash dump and share it privately via a VS ticket, we could investigate more.

Also try turning off analyzers via /p:RunAnalyzers=false to determine whether the problem is in analyzers or the compiler itself.
