And why are there no 'friends' that do not abort?

So what does the allow_failure parameter do?

No, emalloc() and friends abort in case of a memory overflow, Checking
for the return value does not make any sense.

Is a call to exit() graceful request termination?
In my opinion, that's just killing the entire process.
And in the case of a multi-threaded server, that's equivalent to
killing the entire server.
BTW, erealloc has an allow_failure parameter. How about passing true at
/php4/ext/zlib/zlib.c:628?
ZEND_API void *_erealloc(void *ptr, size_t size, int allow_failure
ZEND_FILE_LINE_DC ZEND_FILE_LINE_ORIG_DC)

But /php4/ext/zlib/zlib.c is your code right? Not the code from the
zlib authors?
The bug isn't in zlib owned code, it's in php owned code, and that's
your code.
This code indeed expects to get NULL if erealloc fails.
Is there a flag for erealloc or function to use that doesn't 'cause an
exception' and instead just returns NULL?
s2 = (char *) erealloc(s1,length);
if(! s2) { if(s1) efree(s1); RETURN_FALSE; }

Yes, you're the only one. Report to zlib authors if you don't like
Ilia's reply.
