Same result with php5.3-200808211030 and all releases since (don't know if it happened before).

Can someone please confirm that this occurs only when ext/hash is built as shared?

[2008-09-29 12:44 UTC] olivier at ajeux dot com

New configure/make without "--enable-hash=shared" (replaced with "--enable-hash"): OK
Build complete.

[2008-09-29 14:31 UTC] [email protected]

Greg, please have a look. Phar should properly check for the existence of hash imo.

[2008-09-29 23:57 UTC] [email protected]

I think we can fix this by using php_hash_sha256_ops and php_hash_sha512_ops to extract the actual address of PHP_SHA512Init and company, will try a fix later if I have time, otherwise tomorrow.  Unless Steph beats me to it (check php_hash.h and hash_sha.c, searching for php_hash_sha256_ops to see what I'm talking about)

[2008-09-30 00:02 UTC] [email protected]

another update: this should be completely unnecessary as we include ext/hash/php_hash_sha.h which has:

PHP_HASH_API void PHP_SHA256Init(PHP_SHA256_CTX *);

all defined properly

I wonder if building hash shared prevents the proper export of this function?

[2008-09-30 11:25 UTC] [email protected]

Sorry Greg, would if I could but still have no way to build 5.3. I'll poke Marcus.

This bug has been fixed in CVS.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at
http://snaps.php.net/.
 
Thank you for the report, and for helping us make PHP better.

Unfortunately, the fix is removing support for ext/hash if it is built shared.  This could be revisited in a future release, but would involve extensive code changes to call the PHP versions of hash_init() rather than the C versions, something I don't want to do until 5.3.0 is released.
