Compiler on windows 8.1 issues

[saixmh]

Source compiled to binary can not be run. But after I use UPX to compress the binary, it can be run successfully.

[huonw]

Could you be more specific? E.g. what source? In what way does it fail to run?

[saixmh]

@huonw
Thanks. Anything sources can be compiled but not run. (windows 8.1 chinese)
E.g.

test.rs
fn main() {
    println!("Hello, world!");
}

D:\>rustc test.rs
D:\>test.exe

The error message just like: test.exe has already stop working.
With this information:

Question event name: APPCRASH

I'm sorry for my terrible translations. After compress, it can run normally.

D:\>upx test.exe
...
D:\>test.exe
Hello, world!

@BigBoneDaddy Just running a simple anti virus. But if it has Intercepted virus, It will give me a tip. I also feel very strange.

So rustc runs fine but not binaries created by it?
Does cargo work?
Does it still crash if the println! is removed?

[saixmh]

@retep998
It can created binaries but the binaries can't work.
The cargo can't work, it's the same as the binary which is rustc created.
It still crash without println!

[retep998]

Could you try running a binary created by rustc with gdb and get a backtrace of the point where it crashes?

[saixmh]

@retep998
I try to use gdb and get this info.

@saixmh Can you enter in the command backtrace inside gdb to get a backtrace?

[saixmh]

@retep998 Thanks.

I guess we can chalk up yet another issue to jemalloc being easily broken on Windows.
A workaround for now can be to use the msvc version of Rust, which doesn't use jemalloc. You'll have to install VS 2013 and use Microsoft Visual Studio 12.0\VC\bin\amd64\vcvars64.bat to setup your environment variables so it'll work (at least until #26741 lands). Also unwinding is kinda broken so panics will abort instead, but at least it doesn't use jemalloc.

Also, what command line or terminal are you using? cmd.exe? Git bash? Conemu? Msys2?

[saixmh]

@retep998
Too many thanks.
It's cmd.exe.

[retep998]

Another option you have is to manually build Rust yourself and when doing ./configure you can pass the --disable-jemalloc flag.

[saixmh]

@retep998
All right, I'll try it. Thanks.
