Segmentation fault (SIGSEGV) libclrjit.so`GenTreeVisitor #115515
Description
Description
I am using efcore to query my tables. Recently i got a crash which happens only linux enviroments. I was able to reproduce the bug.
POC repo: https://github.com/risperdal/jitcrashpoc.git
Minimal example looks like this
var services = new ServiceCollection();
services.AddDbContext<ClientDbContext>((serviceProvider, options) =>
{
options.EnableDetailedErrors();
options.UseSqlite($"Data Source=:memory:");
});
var sp = services.BuildServiceProvider();
using var scope = sp.CreateScope();
var cctx = scope.ServiceProvider.GetService<ClientDbContext>();
Console.WriteLine("executing");
await cctx.Database.OpenConnectionAsync();
await cctx.Database.MigrateAsync();
await cctx.example_table.AddAsync(new example_table
{
col_1 = 1
});
await cctx.SaveChangesAsync();
var rows = await cctx.example_table.ToListAsync();
foreach (var item in rows)
{
Console.WriteLine(item.col_1);
}
Console.WriteLine("executed");Reproduction Steps
git clone https://github.com/risperdal/jitcrashpoc.git
cd jitcrashpoc
dotnet run
Expected behavior
should be printing
executing
1
executed
Actual behavior
instead it crashes after printing executing
Regression?
No response
Known Workarounds
If i comment options.EnableDetailedErrors(); it is perfectly working.
Aside from commenting options.EnableDetailedErrors(); line i got it working by changing some column types to double, string and got it working some times with removing columns vice versa
Configuration
I got crashed it on my development machine both WSL2 and regular aspnet docker images. And it is crashing on my production enviroment too.
