Description:
------------
When you call glob() with the GLOB_BRACE flag set, PHP segfaults if
there are no files or directories matching the pattern.
I'm running Apache 2.0.47 and PHP was built with the following
configure line:
'./configure' '--enable-versioning' '--enable-memory-limit'
'--with-layout=GNU' '--with-zlib-dir=/usr' '--disable-all'
'--with-regex=php' '--disable-cli' '--with-bz2=/usr' '--enable-ctype'
'--with-dom=/usr/local' '--enable-exif' '--enable-ftp' '--with-gd'
'--enable-gd-native-ttf' '--enable-gd-jis-conv'
'--with-freetype-dir=/usr/local' '--with-jpeg-dir=/usr/local'
'--with-png-dir=/usr/local' '--with-xpm-dir=/usr/local'
'--with-gettext=/usr/local' '--with-mysql=/usr/local'
'--with-openssl-dir=/usr/local' '--with-openssl=/usr/local'
'--enable-overload' '--with-pcre-regex=yes' '--enable-posix'
'--with-pspell=/usr/local' '--enable-session' '--enable-sockets'
'--enable-tokenizer' '--with-expat-dir=/usr/local' '--enable-xml'
'--with-zip=/usr/local' '--with-zlib=yes'
'--with-apxs2=/usr/local/sbin/apxs' '--with-imap=/usr/local'
'--with-imap-ssl=/usr/local' '--prefix=/usr/local'
'i386-portbld-freebsd4.7'
Reproduce code:
---------------
<?
glob("{*.foo,*.bar}", GLOB_BRACE);
?>
Expected result:
----------------
glob() should return FALSE, indicating that there were no files or
directories matching the pattern.
Actual result:
--------------
PHP exits on signal 11 (segmentation fault), as illustrated by these
entries in my Apache error log:
[Tue Oct 28 22:38:02 2003] [notice] child pid 68645 exit signal
Segmentation fault (11)
[Tue Oct 28 22:38:03 2003] [notice] child pid 68670 exit signal
Segmentation fault (11)
[Tue Oct 28 22:38:12 2003] [notice] child pid 68800 exit signal
Segmentation fault (11)
