Subject: [ruby-core:57023] [CommonRuby - Feature #8864][Open] sprintf	segfaults with too high precision


Issue #8864 has been reported by Aaronneyer (Aaron Neyer).

----------------------------------------
Feature #8864: sprintf segfaults with too high precision
https://bugs.ruby-lang.org/issues/8864

Author: Aaronneyer (Aaron Neyer)
Status: Open
Priority: Normal
Assignee: 
Category: 
Target version: 


In any Ruby version (attempted with 1.8.7, 1.9.3, and 2.0.0), specifying a very large precision in sprintf can cause a segmentation fault.

The following code will cause the segmentation fault.

`"%.99999f" % 10`

The number to cause a segfault is dependent on the system. On my laptop, any number above 1100 would cause it, and on an EC2 micro instance, around 2500 was the limit.
