When I compile PHP use parameters --enable-debug, the period of mistake won't
appear. In return, --disable-debug this parameter compiler, it appeared again.
This is very puzzled

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.
Specifically, we're going to need a backtrace with debug information, I think.
