Failed to run "cargo run" using MinGW-W64 with SJLJ exception handling models

[wh201906]

Hi there.
I use gcc version 8.1.0 (x86_64-posix-sjlj-rev0, Built by MinGW-W64 project) at first.
I failed to run "cargo run" in the instructions and got these errors.

PS E:\Documents\source\rust\hello> cargo run
   Compiling hello v0.1.0 (E:\Documents\source\rust\hello)
error: linking with `x86_64-w64-mingw32-gcc` failed: exit code: 1

error: could not compile `hello` due to previous error

Then I found a page saying that I should use SEH rather than SJLJ.
After installing the SEH version of GCC(x86_64-8.1.0-posix-seh-rt_v6-rev0), the "cargo run" works fine.

Hello, world!

Is this a bug?

[pnkfelix]

is this the same issue as #53301 ?

[wh201906]

I don't know...

[mati865]

Rust doesn't support SJLJ exception model for windows-gnu targets, I'm unaware of any plans to change it.

[wh201906]

If the lack of support in SJLJ exception model is designed so and expected, should I close this issue?

[mati865]

Dunno what the devs think but personally I don't think its useful to keep this open.

[wh201906]

Yeah you are right.
