stackoverflow error in mono-6.12 when compressing data

[itn3000]

Overview

I tried to compress data with ZStdSharp.Compressor, stackoverflow error was occurred and terminated.

Steps to reproduce

1. create new console app project
2. add ZstdSharp.Port-0.7.2 nuget package and set TargetFramework to net48
3. replace Program.cs code to gist code
4. publish app to zstdtest
5. build container image by Dockerfile in above url
6. run container

Expected

output compressed data as Base64 and exit normaly

Actual

stackoverflow error occurred and exited abnomarly with following message

Stack overflow in unmanaged: IP: 0x55db998be9d3, fault addr: 0x7ffc88ab6ff8
Stack overflow: IP: 0x55db998be9d3, fault addr: 0x7ffc88aaeff8
Stacktrace:

  <...>

Addtional

This code was worked as expected in net7.0 and net48+windows. But mono on windows(6.12.0.199), error was reproduced.

Is this reproduced in mono under windows ?

[oleg-st]

Mono doesn't seem to work well with function pointers

reported bug to mono https://github.com/mono/mono/issues/21716

I will make a workaround for this

Workaround is ready, will release a new version in a while.

I'm getting a segmentation fault when running a Xamarin.iOS application. Could it also be due to this?

@jp-pino If it uses mono of the same version, then yes

[oleg-st]
