Issue #16185 has been updated by headius (Charles Nutter). A note just from poking around here... I'm guessing this is due to the reporter's system using a filesystem encoding that uses wide characters, and the Ruby version tested is not handling it well. This issue against Python's pip seems similar: https://github.com/pypa/pip/issues/10858 I know that CRuby has in the past had some bugs around peculiar or non-standard filesystem encodings, like UTF-16 with its wide characters. This may be fixed in more recent versions, but as @jeremyevans0 points out we're pretty far past the AIX freshness date and I would not know how to even confirm this bug, much less fix it if still broken. ---------------------------------------- Bug #16185: basictest failure on AIX 6.1 for 64bit build https://bugs.ruby-lang.org/issues/16185#change-103010 * Author: Reshma (Reshma Kumar) * Status: Open * Priority: Normal * Assignee: kanemoto (Yutaka Kanemoto) * ruby -v: 2.6.3 * Backport: 2.5: UNKNOWN, 2.6: UNKNOWN ---------------------------------------- We are building ruby 2.6.3(both 32 and 64bit) on AIX 6.1.
