_set_se_translator function is used for setting a hook when an exception is triggered in the code.
For testing, we have created an exception the code by null dereferencing.
But, even after the SEH translator hook function is registered, the hook function is not getting triggered when exception had occurred.
What could be the possible reasons?

2025-10-14T16:38:43.4066667+00:00 We have a very large product code, and I am talking about a particular thread.
In the same, thread I am able to see this issue everytime.

2025-10-14T16:44:29.08+00:00 We ensured that _set_se_translator function was invoked from the same thread, where the exception had occurred.

2025-10-14T16:46:16.29+00:00 Is there any good ways to debug this problem?
Or any possible common reasons? Regarding the types of exceptions, or caught in catch block or not?

2025-10-14T16:52:10.4733333+00:00 If code other than yours (e.g., some loaded dll) calls the function to set its own then your callback would be replaced/removed -- "For
_set_se_translator, there are implications when dynamically linking to the CRT; another DLL in the process might call_set_se_translatorand replace your handler with its own."Maybe set a breakpoint on the function to see if its being called by code other than yours.

2025-10-15T02:30:55.6166667+00:00 I tried debugging by setting a breakpoint in the callback. But it was not hit nearby anytime. It means that it's not been replaced by any other program.

Set the breakpoint on the _set_se_translator function.

How did you start the problematic thread?
