I have a repro in case that helps. What's the workaround for this ATM?

sciter-go version: `commit 3bfb52764d8d380076f5dba8fa1a1b38796d27fa Author: golint fixer Date: Thu Oct 25 09:42:49 2018 -0500

Fix golint import path`

sciter-sdk version: `commit 1ac2e536d688b120a16da0b9d33159c3c86b4159 Author: Andrew Date: Sat Mar 16 08:59:44 2019 -0700

[+vlist] fix of the case when list.style["max-height"] == "max-content"`

go file:

package main import ("github.com/sciter-sdk/go-sciter" "github.com/sciter-sdk/go-sciter/window") func main() { rect := sciter.NewRect(0, 100, 860, 600) sciter.SetOption(sciter.SCITER_SET_SCRIPT_RUNTIME_FEATURES, sciter.ALLOW_FILE_IO|sciter.ALLOW_SOCKET_IO|sciter.ALLOW_EVAL| sciter.ALLOW_SYSINFO) windowflags := sciter.SW_TITLEBAR | sciter.SW_RESIZEABLE | sciter.SW_CONTROLS | sciter.SW_MAIN mainWin,_ := window.New(windowflags, rect) mainWin.LoadFile("test.html") mainWin.Show() mainWin.Run() }

test.html (s/</[/g to work around githubs broken code quoting): [html>[head> [script type="text/tiscript"> $(#btnTest).on("click", function () {view.window {url: self.url("crash.html")};}); </script> [/head><body> [button#btnTest>Test</button></body></html>

crash.html (s/</[/g to work around githubs broken code quoting): [html>[head> [script type="text/tiscript" > $(#btnCrash).on("click", function () { view.close(); }); </script></head><body> [button#btnCrash>Crash</button> [/body></html>

With everything in the same folder running (adjust env vars as needed): $ GOROOT=/usr/local/go GOPATH=~/src/includes/go go build -o test test.go && ./test

Get the following: `fatal error: unexpected signal during runtime execution [signal SIGSEGV: segmentation violation code=0x80 addr=0x0 pc=0x7f599e5a0be6]
