Summary0001384: Big red warning during build process
Description

Building my PHP container with xDebug enabled and I get a warning..

In file included from /xdebug-2.5.0/xdebug_handlers.h:23:0,
from /xdebug-2.5.0/php_xdebug.h:33,
from /xdebug-2.5.0/xdebug_handler_dbgp.c:35:
/xdebug-2.5.0/xdebug_handler_dbgp.c: In function 'send_message':
/xdebug-2.5.0/xdebug_com.h:42:23: warning: ignoring return value of 'write', declared with attribute warn_unused_result [-Wunused-result]
#define SSENDL(a,b,c) write(a,b,c)
^
/xdebug-2.5.0/xdebug_handler_dbgp.c:266:2: note: in expansion of macro 'SSENDL'
SSENDL(context->socket, tmp->d, tmp->l);
^

Steps To Reproduce

Using the following command in my Dockerfile ...

RUN \
echo 'Installing Xdebug' && \
wget http://xdebug.org/files/$XDEBUG_VERSION -O xdebug.tgz && \
tar xzf xdebug.tgz && \
rm -f xdebug.tgz && \
cd xdebug-/ && \
phpize && \
./configure --with-php-config=/usr/bin/php-config && \
make && \
export TEST_PHP_ARGS='-n' && \
make test && \
make install && \
cd .. && \
rm -Rf xdebug-/

Additional Information

xDebug works as expected, so really this is a 'just in case it is important and/or specific to an environment' sort of thing.

TagsNo tags attached.
Operating System
PHP Version7.0.10-7.0.14

Not particularly important, but the fix is easy too.

I can't reproduce this. With which GCC version is this (run gcc --version)?

I still can not reproduce this with gcc 5.4 - can you give me all the steps necessary to reproduce this? Assume I have docker installed, but that I don't know how to use it.

I could reproduce this on Ubuntu 16.04 with GCC 5.4, and have now made a PR: https://github.com/xdebug/xdebug/pull/320 that will make it into 2.6.0dev.
