Pain point

Errores de segmentación (SIGSEGV) al integrar librerías Go compiladas con c-shared y llamadas desde C# debido a conflictos en la gestión de señales y memoria entre ambos runtimes.

Who'd pay for this

Equipos de desarrollo de software que integran componentes en Go y C# en aplicaciones críticas, especialmente en empresas de software que requieren alta estabilidad en sistemas híbridos.

We hit an SIGSEV when running building a Go library with c-shared and then calling it from C#. The issue seems difficult to trigger under normal workflows, but I've managed to narrow the issue down to a reproducer that heavily triggers C# GC and calls Go library in a busy loop. https://gist.github.com/egonelbre/18432be81e1a4e18887e1590ead6f496 AI analysis seems to point that the issue is that Go installs its own sigaltstack and then C# triggers a signal due to it's own GC, which then arrives at a sigaltstack that has been freed. I'm still trying to find a workaround, but I have not found one yet. Installing a custom larger sigaltstack seems to improve things, but it still seems to crash. ### What did you see happen? The failure looks like ``` [dotnet-repro] mode=signal workers=32 iters=1000000 interval=50µs gc=True pid=4300 timeout: the monitored command dumped core ./run.sh: line 35: 4299 Segmentation fault timeout 60 env LD_LIBRARY_PATH=. DOTNET_CLI_HOME=/tmp "$DOTNET_BIN" exit=139 === SIGSEGV on attempt 1 — reproduced ``` ### What did you expect to see? No SIGSEGV. Alternatively, if there's a workaround, it would be nice to have some documentation on how to correctly set it up.
