Subject: [Bug regex/11159] lock contention within regexec() when used from multiple threads
Date: Mon, 11 Jan 2010 17:55:00 -0000	[thread overview]
Message-ID: <20100111175517.24626.qmail@sourceware.org> (raw)
In-Reply-To: <20100111094018.11159.extproxy@gmail.com>


------- Additional Comments From bonzini at gnu dot org  2010-01-11 17:55 -------
The fact that is "const" does not mean that no internal data structures are
modified (and this needs locking).  C++ even has a "mutable" keyword for this. 
glibc does the locking per-regex_t.

Could be a doc bug, leaving this decision to the glibc maintainers.
