Comment (by gk):

 Okay, let's go with plan d): Alex Crichton pointed me to
 https://github.com/rust-lang/rust/pull/49633 a while ago as a potential
 stopgap solution. It turns out that one works in the sense that 32bit tor
 for Windows with Rust enabled is still compiling and running AND that I am
 now hitting #26326.

 I'll post a proper patch for this bug once I can verify that Tor Browser
 properly compiles and runs.

 If that still hits some problems we could think about plan e) to ditch
 SjLj exception handling for 32bit Windows in favor of Dwarf2 or we could
 think about resorting to the official std lib for the time being.
