Subject: [PATCH] httpd: undefine ruby_snprintf alias for non-Ruby processes
Date: Sun, 8 Jan 2023 18:41:31 +0000 [thread overview]
Message-ID: <20230108184131.22288-1-e@80x24.org> (raw)
ruby/subst.h (included by ruby.h) replaces `snprintf' with
`ruby_snprintf'. This only works in processes linked to Ruby,
but won't work in subprocesses spawned by Ruby.
