embedded linux-arm dotnet 6/7 segmentation fault

[BennyBread]

Is there an existing issue for this?

Describe the bug

We have an embedded linux system on which dotnet5 runs without problems.

I tried to upgrade to dotnet 6 or 7 but the newer dotnet versions do not run.

When I try to start dotnet it cashes:

root@dev:/dotnet-7# ./dotnet
Segmentation fault (core dumped)
root@dev:/dotnet-7#

dotnet-6 and dotnet-7 both produce the same output.

All the dotnet Versions where downloaded from official site:

aspnetcore-runtime-5.0.17-linux-arm.tar.gz aspnetcore-runtime-6.0.13-linux-arm.tar.gz aspnetcore-runtime-7.0.2-linux-arm.tar.gz

dotnet5 runs without problems:

root@dev:/# dotnet --info

Host (useful for support):
  Version: 5.0.17
  Commit:  6a98414363

.NET SDKs installed:
  No SDKs were found.

.NET runtimes installed:
  Microsoft.AspNetCore.App 5.0.17 [/deprag/dotnet/shared/Microsoft.AspNetCore.App]
  Microsoft.NETCore.App 5.0.17 [/deprag/dotnet/shared/Microsoft.NETCore.App]

To install additional .NET runtimes or SDKs:
  https://aka.ms/dotnet-download
root@dev:/dotnet-7#

dotnet --info does of course also not run at all.

We'd really highly appreciate it to upgrade to dotnet 7...

Expected Behavior

dotnet executable and the "user programs" runs on the system..

Steps To Reproduce

When I start dotnet 6 or 7 using gdb I get this output:

root@dev:/dotnet-7# gdb ./dotnet

@BennyBread this is almost certainly something on the runtime side of the fence rather than ASP.NET, can you confirm that you are just trying to invoke the dotnet executable and there is no ASP.NET code involved yet? (that is what it looks like from the command-line invocations listed above).

[BennyBread]

@mitchdenny There is no user code involved at all. I'm only try to run the dotnet command without any parameters.

dotnet 5 executable runs with no problems on the system. net6 and 7 does not. Is there any possibility to find out what's missing on that system? (I'ts an embedded system on a controller we sell)

[mitchdenny]

OK, I'm going to transfer this to to dotnet/runtime since this is more there area.

Hello @BennyBread, what distro are you trying this on? Are you able to provide a dump to investigate further? Thx!

[BennyBread]

@mangod9 It's an distro from TI K2G with some minor changes in the kernel. I can provide a gdb coredump, uploaded it here: gdb core dump Hope this helps.

I have the same problem, different development versions, and .NET 8 is currently the same problem. Are there any progress or news?

Or should I give up using .NET development

embedded linux-arm?
