() Previous Comments: ------------------------------------------------------------------------ [2005-12-01 18:04:58] sniper@php.net We can't reproduce this so please provide the backtrace. (without --enable-debug if that's the only way..) ------------------------------------------------------------------------ [2005-12-01 16:31:23] minnoce at polito dot it Obviously, the expected output is: TESTTEST ------------------------------------------------------------------------ [2005-12-01 16:28:50] minnoce at polito dot it mmm... Compiling PHP with --enable-debug and reproducing the bug (getting the "test.html" with the two include virtuals) don't cause anymore segmentatio faults. But simply the last "include virtual" produce NO output at all (no errors in apache logs). The output received from browser getting "test.html" is: TEST Thanks, Mauro ------------------------------------------------------------------------ [2005-12-01 15:58:54] sniper@php.net Please provide current backtrace. And make sure you had --enable-debug in your configure line! Also, don't submit ALL the lines, just the relevant ones. (The "loading symbols.." lines are not needed) ------------------------------------------------------------------------ [2005-12-01 15:48:55] minnoce at polito dot it The bug persist even with the LATEST PHP 5.1 from CVS. The GDB backtrace is exactly the same already reported.
