Exactly. I've been using _set_se_translator in various projects in the
past and I never had to build with /EHa except for the tiny fraction of
code at the catch site. C++ exceptions are nothing but Windows
structured exceptions with a special tag. Therefore it doesn't matter at
all which build option is used at the throw site. You can even get away
without the /EHa and _set_se_translator shebang if you stick with
__try/__except and cast the exception info into a std::exception_ptr or
do whatever else you have to.
