Comment (by gk):

 Replying to [comment:2 tom]:
 > Hm. I know that mingw-clang-x86 needs sjlj-exceptions because the
 default SEH exceptions are not supported there.  But I'm confused why Tor
 needs a special case and the Mozilla builds don't.

 What do you mean with special case? I doubt you are cross-compiling Rust
 for 32bit Windows. But we do mainly to be able to react "quickly" to
 potential reproducibility issues (see the infamous #26475 where this
 stance has helped).
