[canavan]

When compiling PHP with -pg, the resulting build cannot be installed, since the installation of pear fails with

Fatal error: Maximum execution time of 0 seconds exceeded in /tmp/pb/pear/install-pear-nozlib.phar on line 2

Tested with the default gcc of zesty as well as gcc-7 7.2.0-8ubuntu3 on artful with PHP 7.1.10 and 7.1.11.

Unpack PHP source code in e.g. /tmp/p, then reproduce with

    mkdir -p /tmp/pb

    cd /tmp/pb && \

    CFLAGS=" -pg -fPIC" \

    /bin/bash /tmp/p/php-7.1.11/configure \

        --enable-fpm \

        --disable-all \

        --prefix=/tmp/pi \

        --without-openssl \

        --without-mm \

        --without-mcrypt \

        --enable-pcntl \

        --enable-ctype \

        --enable-posix \

        --with-pcre-regex=/usr/ \

        --with-pear \

        --enable-phar \

        --enable-xml \

        --enable-libxml \

        --with-iconv \

        --without-gd \

        --with-zlib \

        --without-curl \

        --enable-fd-setsize=8192 \

        --enable-opcache \

        --without-sqlite3 \

        --without-pdo-sqlite \

        --without-pdo-mysql \

        --without-pgsql \

        --without-pdo-pgsql && \

    (cd /tmp/pb; nice make -j 4 install V=1)
