Would you please consider to add an extra ./configure setting to skip the check in sqlite3 extension as it is the only one that explicitly refuses the -ffast-math flag? Test script: --------------- CC=/opt/bin/gcc CFLAGS="-O2 -msse4.2 -ffast-math -fomit-frame-pointer -fno-stack-protector -fno-exceptions" ./configure --prefix=/opt/php7 --enable-opcache Expected result: ---------------- Compilation succeeds. Actual result: -------------- gcc-5.1.0 gave: /Users/xx/box/php-src/ext/sqlite3/libsqlite/sqlite3.c:23512:3: error: #error SQLite will not work correctly with the -ffast-math option of GCC. # error SQLite will not work correctly with the -ffast-math option of GCC. ^ ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69928&edit=1
