--disable-debug affects the display of the memory leak :-)
It does not affect the error itself. Still an increasing load.
I've added some trace warnings, and it seems that every string is
passed through php_escape_html_entities twice! Here's an anonimized
snippet:

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?
