Description:
------------
包括 Solaris，Mac OS X，Oracle Linux 和 BSD
在内的很多操作系统 都提供了 DTrace
跟踪调试框架，它永远可用，并且额外消耗极低。
DTrace
可以跟踪操作系统行为和用户程序的执行情况。
它可以显示参数值，也可以用来分析性能问题。
用户可以使用 DTrace D
脚本语言创建脚本文件来监控探针，进而高效分析数据指针。

除非用户使用 DTrace D 脚本激活并监控 PHP
探针，否则它并不会运行，所以不会给正常的应用执行带来任何性能损耗。
即使 PHP
探针被激活，它的消耗也是非常低的，甚至可以直接在生产系统中使用。

Test script:
---------------
# modprobe fasttrap
# chmod 666 /dev/dtrace/helper

Build PHP with the --enable-dtrace configuration parameter:

# ./configure --enable-dtrace ...
# make
# make install
#!/usr/bin/env bash

rm .rbenv-version 2>/dev/null

VERSIONS=$(phpenv versions --bare)
SCRIPT_DIR=$(dirname $0)

for v in $VERSIONS system; do
  echo -n "$v: "
  if ${SCRIPT_DIR}/test-build.sh $v >$v.log 2>&1; then
    echo -e "\033[1;32mPASS\033[0m"
  else
    echo -e "\033[1;31mFAIL\033[0m"
  fi
done
