Issue #9752 has been reported by Naohisa Goto. ---------------------------------------- Bug #9752: r45598 causes Errno::EINVAL on Solaris https://bugs.ruby-lang.org/issues/9752 * Author: Naohisa Goto * Status: Open * Priority: Normal * Assignee: Nobuyoshi Nakada * Category: * Target version: * ruby -v: ruby 2.2.0dev (2014-04-17) [sparc64-solaris2.10] * Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN ---------------------------------------- On Solaris, after r45598, the following error occurs. <pre> ./miniruby: Invalid argument - getcwd (Errno::EINVAL) </pre> It seems that getcwd(NULL, 0) is not supported in Solaris. The Solaris man page of getcwd(3c) says: <pre> If buf is a null pointer, getcwd() obtains size bytes of space using malloc(3C). The pointer returned by getcwd() can be used as the argument in a subsequent call to free(). </pre> But no description when the size is zero. -- https://bugs.ruby-lang.org/
