Issue #15151 has been reported by chopraanmol1 (Anmol Chopra). ---------------------------------------- Bug #15151: String#slice!(0,..) creates a duplicate of original string https://bugs.ruby-lang.org/issues/15151 * Author: chopraanmol1 (Anmol Chopra) * Status: Open * Priority: Normal * Assignee: * Target version: * ruby -v: ruby 2.6.0dev (2018-09-23 trunk 64815) [x86_64-linux] * Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN ---------------------------------------- String#slice! when used at beginning of string (e.g. slice!(0,10) calls rb_str_drop_bytes which creates shared string for non embed string. str_modify_keep_cr clears the flag of shared string which is called before rb_str_drop_bytes. Due to which while calling slice! multiple time on same string creates multiple duplicate string.
