为什么在Compiler Explorer上的Visual Studio忽略“异常模型"设置? [英] Why is Visual Studio on Compiler Explorer ignoring the Exception Model setting?

问题描述

当我尝试在 Compiler Explorer测试用例中使用/EHs标志时，(启用通过extern "C"函数传递的异常)，VC ++ 19.22似乎忽略了它，因为它仍然会踢出C5039而不实际更改代码.

When I try to use the /EHs flag in a Compiler Explorer testcase (to "enable" exceptions passing through extern "C" functions), VC++ 19.22 seems to be ignoring it, based on it still kicking out a C5039 and not actually changing the code.

我想念什么?我忘记了其他开关吗?

What am I missing? Have I forgotten another switch or something?

• 基本案例cmdline:/O1 /EHsc /Wall /wd4571
• 测试用例cmdline:/O1 /EHs /Wall /wd4571

• Base case cmdline: /O1 /EHsc /Wall /wd4571
• Test case cmdline: /O1 /EHs /Wall /wd4571

推荐答案

嗯，看起来Compiler Explorer设置了异常模型本身，并且它具有优先权.

Ah, looks like Compiler Explorer sets the exception model itself, and this is taking precedence.
