>Description:
Broken thread support with configure --enable-threads. After install the port "memcached -h" output didn`t show -t switch (thread number)
With configure script patch memcached core dumped after setting thread number.
>How-To-Repeat:
Put into /usr/ports/databases/memcached/Makefile.local:
CONFIGURE_ARGS+= --enable-threads
Then:
make -C /usr/ports/databases/memcached configure
...
checking for socklen_t... yes
checking for endianness... little
test: x: unexpected operator
checking for mlockall... yes
...
After fix this error:
memcached -t8 -u root
Segmentation fault (core dumped)
