[ruby-core:107764] [Ruby master Bug#18604] [BUG] ERROR(VpDivd): space for remainder too small

From: "nobu (Nobuyoshi Nakada)" <noreply@...>
Date: 2022-03-02 10:24:00 UTC
List: ruby-core #107764
Issue #18604 has been updated by nobu (Nobuyoshi Nakada).

Status changed from Open to Third Party's Issue

Seems fixed by BigDecimal 3.1.2.

----------------------------------------
Bug #18604: [BUG] ERROR(VpDivd): space for remainder too small
https://bugs.ruby-lang.org/issues/18604#change-96689

* Author: mentalizer (Jakob Skjerning)
* Status: Third Party's Issue
* Priority: Normal
* ruby -v: ruby 3.1.1p18 (2022-02-18 revision 53f5fc4236) [arm64-darwin21]
* Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN
----------------------------------------
After upgrading to Ruby 3.1 one of our statistical dashboards started crashing with a message saying

    [BUG] ERROR(VpDivd): space for remainder too small

### How to reproduce

This can be reproduced in irb (reproduction script is attached containing the below code):

``` ruby
$ irb
3.1.1 :001 > require "bigdecimal"
 => true
3.1.1 :002 > 1.0 / BigDecimal("0.9652409267836026803310997240835632636973e2")
```

### Actual result

```ruby
(irb):2: [BUG] ERROR(VpDivd): space for remainder too small.
ruby 3.1.1p18 (2022-02-18 revision 53f5fc4236) [arm64-darwin21]

-- Crash Report log information --------------------------------------------
...

```

Full output from running reproduction script has been attached.

### Expected results

The result of division, which is roughly:

```
 => 0.10360107743589181177761764314914637186293143963577706371029263e-1
```

### Affected Rubies

So far I've been able to reproduce this on...

- ruby 3.1.1p18 (2022-02-18 revision 53f5fc4236) [arm64-darwin21]
- ruby 3.1.1p18 (2022-02-18 revision 53f5fc4236) [x86_64-linux]
- ruby 3.1.0p0 (2021-12-25 revision fb4df44d16) [arm64-darwin21]

The following seem to work just fine:

- ruby 3.0.3p157 (2021-11-24 revision 3fb7d2cadc) [arm64-darwin21]

### Notes

Admittedly, the precision here is way higher that we actually need it to be, and our workaround has been to simply convert the BigDecimal to Float before dividing.

```ruby
1.0 / BigDecimal("0.9652409267836026803310997240835632636973e2").to_f
# => 0.010360107743589182
```
