Description

I have no idea why, but my instance of gitea crashs with a SIGSEGV every time when the webhook start. Hook target is my PHP site and second hook is Redmine. I have many repos and every repo have the same webhooks

[tomas-kulhanek]

@lunny i think this is same problem like #1408 because when i try what @tboerger says webhooks working fine.

[tboerger]

Maybe we should check if we can enforce the go name resolver within our prebuilt binaries.

[tboerger]

Looks like we have to build the binary with the build tag netgo, because the default netcgo seems to fail on some systems. It have been introduced with golang/go@b615ad8

[tboerger]

I have created the pull request #1690 which should solve this issue as it enforces the Go name resolution instead of CGO for cross-compiled binaries.

[tomas-kulhanek]

After deploy master version ddb63a7 and test of webhook, gitea still working after 2 hours. Thanks for quick fix.
