最近在开发一个基于electron的单页应用时遇到个头疼问题，想请教各位高手帮忙支支招。（技术选型是electron + webpack）
问题是这样的，每当打开并运行这个app后，当我的输入法调成系统自带的简体拼音，并用鼠标点击页面上某个input元素或textarea元素或某个可点击元素时（如设置了cursor:pointer的div元素），app会闪退。
此时查看ide控制台的报错信息会发现如下信息：
Electron(9467,0x7fffeed5c3c0) malloc: *** mach_vm_map(size=18446744073709543424) failed (error code=3)

奇怪的是app唯独在新版的macbook pro2017上运行时会出现此问题，而且出现问题时貌似与输入法设置也有关系，默认输入法设置为简体拼音时点着点着就会出现这个问题，如果默认输入法设置为其他则不会。
想请教下各位高手该如何解决？谢谢！
