编译失败

$\ \ \ \ \ \ \ \ \ \ \ \$/tmp/compiler_ae41h5ou/src: 在函数‘void tpre(long long int)’中:
/tmp/compiler_ae41h5ou/src:29:2: 警告：this ‘if’ clause does not guard... [-Wmisleading-indentation]
if(tf==n)return;tf=n;
^~
/tmp/compiler_ae41h5ou/src:29:18: 附注：...this statement, but the latter is misleadingly indented as if it were guarded by the ‘if’
if(tf==n)return;tf=n;
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \$^~

然后当我把tf=n;前面换了个行之后直接就给我返回编译失败，下面一点信息也没有，就像这样
