Previous Comments: ------------------------------------------------------------------------ [2003-07-10 03:03:40] druid at mail dot cz I tried php-5b1 and it is nearly the same, except the gdb output: Program received signal SIGSEGV, Segmentation fault.

I've tested it with sapi. I've got the latest gcc and glibc: Reading specs from /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3/specs Configured with: ../gcc-3.3/configure --prefix=/usr --enable-shared --enable-threads=posix --with-slibdir=/lib --enable-__cxa_atexit --enable-clocale=gnu --enable-__vt_8iostream Thread model: posix gcc version 3.3 ./configure --with-apxs2=/usr/local/apache/bin/apxs \ --with-zlib --enable-bcmath --with-bz2=shared --enable-calendar \ --enable-exif --enable-ftp --with-ttf --with-gettext \ --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir \ --with-mysql --with-mysql-sock --with-recode=shared \ --with-imap --with-imap-ssl=/usr/local/ssl \ --enable-debug glibc-2.3.2 Reproduce code: --------------- SAPI_API void sapi_initialize_empty_request(TSRMLS_D) { SG(server_context) = NULL; SG(request_info).request_method = NULL; SG(request_info).auth_user = SG(request_info).auth_password = NULL; SG(request_info).content_type_dup = NULL; } The last line is the problem.
