[ruby-core:70913] [Ruby trunk - Bug #11551] Segfault for unidentified reasons

[sean]

Issue #11551 has been updated by Sean Griffin.


There is a typo in the `method_missing` definition which is the cause here. Changing `attribute_defintion` to `attribute_definition` fixes it, so the bug appears to have something to do with a `method_missing` invocation when it's defined this way.

I've tried to create an isolated script to reproduce the problem, but haven't been able to thus far. I'll keep seeing if I can, but at the moment it appears to be a weird interaction between the code linked and the rest of rails.

Aha, I got it. It has to do with minitest. Reproduction script: https://gist.github.com/sgrif/720b7473c5ce9a51d6e2

[ruby-core:71011] [Ruby trunk - Bug #11551] [Rejected] `[BUG] cfp consistency error` for unidentified reasons

[nobu]

Issue #11551 has been updated by Nobuyoshi Nakada.

Status changed from Feedback to Rejected

It occurred a system stack overflow.
Ruby tries to catch it as possible, but it is very hard (or nearly impossible) to handle it flawlessly, as it can occur in a critical section, other external libraries, and so on.
