ID: 11676 Updated by: derick Reported By: valerio@wnet.it Old-Status: Open Status: Feedback Bug Type: Scripting Engine problem Operating system: PHP Version: 4.0 Latest CVS (2001-06-25) Assigned To: Comments: You don't need to set the CFLAGS yourself, the -O9 is known to cause problems. Please try to compile without setting ANY CFLAGS yourself. Derick Previous Comments: --------------------------------------------------------------------------- [2001-06-27 14:30:05] valerio@wnet.it Here it is: CFLAGS="-O9 -funroll-loops -ffast-math -malign-double -mcpu=pentiumpro -march=pentiumpro -fomit-frame-pointer -fno-exceptions" ./configure --with-apache=../apache_1.3.20 --with-mysql --disable-debug --with-gnu-ld --enable-memory-limit --enable-inline-optimization I don't remember exactly, but i think i had tried removing ALL gcc optimization options, with the same results... During another crash (pre-crash actually :) i managed to backtrace a httpd which had this stack: #0 0x4012c238 in chunk_free () #1 0x4012bfaa in __cfree () #2 0x80fb8f2 in _efree () The other httpd i backtraced had all the stack like this: #0 0x4012c23e in chunk_free () #1 0x4012bfaa in __cfree () #2 0x80fbcbf in shutdown_memory_manager () Hope this helps... --------------------------------------------------------------------------- [2001-06-27 11:57:34] sniper@php.net what was the configure line used to configure PHP ? --------------------------------------------------------------------------- [2001-06-26 14:32:38] zeev@php.net Ignore the last comment, wrong bug report :) --------------------------------------------------------------------------- [2001-06-26 14:31:52] zeev@php.net Output buffering indeed cannot be used inside output handler functions. However, the code that handled that error situation contained a bug that caused PHP to enter an infinite loop. This bug is now fixed (although the limitation of not being able to use output buffering inside output handlers still applies) --------------------------------------------------------------------------- [2001-06-26 07:32:26] valerio@wnet.it Well, the problem is that we have many virtual hosts on that server, each using it's own log file... I can confirm that the gdb trace for ALL the many dead process, which are in running state, gives the three lines: #0 0x4012c23e in chunk_free () #1 0x4012bfaa in __cfree () #2 0x80fbcbf in shutdown_memory_manager () (it happened this morning too) Is there some way to know which script was executing just before the child died, please tell me! --------------------------------------------------------------------------- The remainder of the comments for this report are too long.
