g++: error: -fsanitize=address is incompatible with -fsanitize=thread

[rizen]

On CentOS 6.5 with g++48 and Perl 5.18.2 I'm unable to compile Memcached-libmemcached. I get this error:

g++: error: -fsanitize=address is incompatible with -fsanitize=thread

Here's the configuration summary:

The funny thing is that there is a package for CentOS for libmemcached, so if this module would just use that, then I could install that package and it would get around this problem.

This was apparently fixed in libmemcached 1.0.18, which is in the repo for this module. Is there any plan on releasing 1.001800 to CPAN? The changes file suggests it was released on April 7, but I only see 1.001702 on CPAN.

There's actually some discussion in a private thread about the upgrade. The
problem is that 1.0.18 broke the build for other people, so it's not a
clean upgrade.

I need to do some testing, but the bug is here:

#11

And here:

https://bugs.launchpad.net/libmemcached/+bug/1304124

And a possible workaround here:

#13

I will try to get something released by this weekend.

Any updates on this? I'm getting the same error since I upgraded to Ubuntu 14.04

Apolgoies, my free time has become rare. I can't commit to getting anything done on this any time soon; but we've put the module into "NEEDHELP" - so if someone wants to help maintain, we'd be glad to have them.

Any updates on this? I'm getting the same error on CentOS 7.

A trial release incorporating libmemcached 1.0.18 is available from
