问题描述
使用 MASM 从 IDA 编译导出的程序集时，出现以下两个错误：
test.exe.asm(32767) : Fatal error A1019: invalid debug and browser data; file exceeds line limit
test.exe.asm(2697) : error A2068: instruction prefix not allowed
mov eax,ds:dword_40D028
test eax,eax
jz short loc_401D40
rep retn <----- Line 2697
首先：这些错误是怎么发生的？原来的 .exe 工作正常。显然反汇编不能产生准确的原始程序集，但它至少应该产生工作代码，不是吗？
其次：我该如何解决这个问题？
编辑：尝试使用 JWASM 编译程序集时，我不再遇到超出行数限制的错误，而是出现以下错误：
