[ruby-core:33185] [Ruby 1.9-Bug#4047] Embedded Ruby issues

From: Garthy X <redmine@...>
Date: 2010-11-15 02:36:06 UTC
List: ruby-core #33185
Issue #4047 has been updated by Garthy X.

File crashtest-20101115a.tgz added

Short version: Whatever the original cause of the crash, things seem to be working fine now.

Long version:

Okay, I've run through around 4000 iterations each with these configurations:

- CentOS 5.3 (base install, not updated) Ruby 1.8.3
- CentOS 5.3 (base install, not updated) Ruby 1.9.2-p0
- CentOS 5.3 (base install, not updated) Ruby 1.9.1-p378
- CentOS 5.3 (base install, not updated) Ruby Nightly snapshot 20101112
- Ubuntu 9.10 (updated fairly recently) Ruby 1.8.3
- Ubuntu 9.10 (updated fairly recently) Ruby Nightly snapshot 20101112

The original symptoms were a crash usually after about 100-200 iterations. 4000 iterations suggests the problem may be gone. The particular system it was run on seemed to affect the results (some seemed immune). It also only manifested with "-pg", as far as I could tell.

It is possible that the systems I tried it on are sufficiently different to the older ones that the bug no longer exists. Unfortunately, these systems are now long gone, so I cannot try them out.

It could also have been related to the compiler or compilation; I had to patch math.c in the 1.8.* series and cont.c in the 1.9* series to get them to build this time around (gcc 4.4.1 on Ubuntu 9.10, updated). I didn't have to do this previously.

It is also possible that I had a similar problem in my project at the time that was similar to the one in the test code, and it just happened to work most of the time on certain systems, whilst crashing frequently on others.

I'll run some longer overnight tests the next few days to be sure, but if there is indeed a bug in Ruby at this point, I can't reproduce it any more. Whatever the original cause, things appear to be working fine now.

Updated crash test code included as attachment.

Thankyou again Nobuyoshi Nakada for having a look at it and for finding and fixing the fault in my sample code.
