Spurious access violation (exit code: 3221225477) when compiling libsyntax with MSVC #50604
Comments
cc @Zoxc Can you try to reproduce? |
I haven't seen this locally. Does it happen often? |
As shown in the post, twice in the last 8 days so far. There are 3 other segfaults on Windows which might also be attributed here (#50000 (comment), #50418 (comment), #50466 (comment)). |
…richton AppVeyor: Read back trace from crash dump on failure. This is an attempt to debug spurious access violations on Windows (rust-lang#33434, rust-lang#50604). Thanks to rust-lang#50276, there should be minidumps to read when rustc segfault. (The implementation is based on <https://github.com/springmeyer/travis-coredump/blob/master/test.bat>.)

Have this occurred this week? |
It's been a while; has anyone seen this lately? |
happens at this code when running on particular machines build with
but it works fine on my laptop. This happens due to missing something wgpu dynamically links against? |
@DhruvDh hi, could you file a new issue for that? This issue only tracks spurious failure from Rust's CI and thus unsuitable for problems in user code. |
sorry, I did not realize that. |
Now that libsyntax is now renamed and splitted and crates structure changed a lot since then, i'd suggest we just close this? |
Symptom: On MSVC builders (Windows), when compiling libsyntax in either stage0 or stage1, the compiler
rustc
will crash with exit code 3221225477 (= 0xc0000005 = access violation).We suspect this is related to #50329 (merged at 2018-05-02T10:13:06Z).
