Well you should really have said you were using the PCH because it is a known issue and a patch is available at https://github.com/Alexpux/MINGW-packages/blob/master/mingw-w64-gcc-git/0010-Fix-using-large-PCH.patch . ------------------ Best regards, lh_mouse 2016-08-23 ------------------------------------------------------------- 发件人：leon zadorin <leonleon77@xxxxxxxxx> 发送日期：2016-08-23 09:06 收件人：gcc-help 抄送： 主题：Re: Re: GCC ICE bug with segfault...
