But in release mode CGI part cores even when it reads php.ini file during "make test". And mod_php behaves as written before... Here is the part of core file after "make test" (sorry but without debug). #0 0x808644f in ?? () #1 0x808605e in ?? () #2 0x808856f in ?? () #3 0x80886c3 in ?? () #4 0x8088649 in ??

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 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. ------------------------------------------------------------------------ [2004-03-28 11:44:52] krasnov at euroweb dot ru A little addition: EVERY test made by "make test" after compilation got FAILED. ------------------------------------------------------------------------ [2004-03-28 11:31:24] krasnov at euroweb dot ru I must notify you that a cannot reproduce this bug when I add --enable-debug to ./configure ------------------------------------------------------------------------ [2004-03-28 11:17:17] krasnov at euroweb dot ru This nasty bug also is being reproduced under FreeBSD 4.8 RELEASE when I try linuxthreads for apache worker thread model. Either HUP or graceful restart of apache 2.0.49 causes log entry like "[notice] seg fault or similar nasty error detected in the parent process" CFLAGS='-O -pipe -march=pentiumpro -DZTS -D__USE_UNIX98 -D_REENTRANT -D_THREAD_SAFE -DHAVE_BROKEN_REALPATH -I/usr/local /include/pthread/linuxthreads -L/usr/local/lib -llthread -llgcc_r' \ LIBS='-L/usr/local/lib -llthread -llgcc_r' \ ./configure \ --prefix=/usr/local/php \ --with-apxs2=/usr/local/apache2/bin/apxs \ --with-openssl \ --with-mysql=/usr/local/mysql \ --with-zlib \ --with-gd \ --with-jpeg-dir=/usr/local/lib \ --with-png-dir=/usr/local/lib \ --with-imap=/usr/local/src/imap-2002d \ --with-imap-ssl=/usr \ --with-gettext \ --with-xml \ --with-tsrm-pthreads 4.3.4 with identical config runs fine... PS: Native FreeBSD 4.8 pthreads run also fine. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
