-Status: Open
+Status: Analyzed
Bug Type: Apache2 related
Operating System: BSD/OS 4.2
PHP Version: 4.4-dev
New Comment:
The problem is in the recent changes to ext/standard/info.c which is
calling php_escape_html_entities (via php_info_html_esc) and PUTS()-ing
the result.
It never efree's it.
I suspect the loading problems will go away if you build a
--disable-debug version of PHP.

PHPAPI char *php_escape_html_entities(unsigned char *old, int oldlen,
int *newlen, int all, int quote_style, char *hint_char
set TSRMLS_DC)
{
int i, j, maxlen, len;
char *replaced;
enum entity_charset charset = determine_charset(hint_charset
TSRMLS_CC);
int matches_map;
maxlen = 2 * oldlen;
if (maxlen < 128)
maxlen = 128; replaced = emalloc (maxlen); // #line 667
len = 0;
i = 0;
while (i < oldlen) {
....
}
}
replaced[len] = '\0';
...
So what happens if oldlen = 0 and more importantly: how can oldlen
become 0?

About the Apache-2 comment:
I haven't been able to use it for anything else than an image server,
since neither mod_perl nor php work well.
Indeed - threads and dynamic linking are a different flavour on BSD/OS.
SIGHUP and SIGUSR are broken in apache2 without php as well, but they
do a SIGTERM/SIGKILL and are then able to restart. With php compiled in
this breaks with a segfault.
