PHP CVS sometimes give sources instead parsed script

Hi, with the current cvs version, my webserver results sometimes the source code instead of the parsed script. Is a knows problem ? I'm using glibc 2.1.3 gcc 2.95 and this configure parameter: CFLAGS="-O3 -mcpu=i686 -march=i686 -fomit-frame-pointer" nice -n 18 ./configure --enable-memory-limit --enable-trans-sid --with- apxs=/usr/local/apache/current/bin/apxs --with-config-file-path=/etc -- with-curl=shared,/usr/local/curl/current --with- mhash=shared,/usr/local/mhash/current --with- mysql=/usr/local/mysql/current --with-mm=/usr/local --with-zlib --with- mcrypt=shared,/usr/local/libmcrypt/current --with-gd=shared,php --with- jpeg-dir=/usr/local --with-png-dir=/usr/local --with-freetype- dir=/usr/local --disable-short-tags --disable-overload --disable-posix --disable-ctype --disable-tokenizer --disable-mbstring --disable-debug Regards, Holger
