php5: calling curl_version() results in bus error

[joe@…]

Most curl functions seem to work normally from php. However, calling curl_version() in a script doesn't work. When called from /opt/local/bin/php, the result is 'Bus error'. When called via FCGI, the php backend dies without output.

OS X 10.4

$ port
MacPorts 1.520

$ /opt/local/bin/php -v
PHP 5.2.5 (cli) (built: Nov 13 2007 18:23:58) 

$ /opt/local/bin/curl -V
curl 7.17.1 (i386-apple-darwin8.10.1) libcurl/7.17.1 zlib/1.2.3
Protocols: tftp ftp telnet dict http file 
Features: Largefile libz

curl_version() seems to return an array, not a string, and it works fine for me, on a MacBook Pro, with Mac OS X 10.4.11, Xcode 2.4.1, MacPorts 1.6.0-rc3, php5 5.2.5_1 and curl 7.17.1_0.

$ /opt/local/bin/php -r 'print_r(curl_version());'
Array
(
    [version_number] => 463105
    [age] => 3
    [features] => 540
    [ssl_version_number] => 0
    [version] => 7.17.1
    [host] => i386-apple-darwin8.10.1
    [ssl_version] => OpenSSL/0.9.8g
    [libz_version] => 1.2.3
    [protocols] => Array
        (
            [0] => tftp
            [1] => ftp
            [2] => telnet
            [3] => dict
            [4] => http
            [5] => file
            [6] => https
            [7] => ftps
        )

)
$

Does this work for you?

[joe@…]

Same problem as before. 10.4.11 on a MacBook, Xcode 2.4.1

$ /opt/local/bin/php -r 'print_r(curl_version());'
Bus error

[ryandesign (Ryan Carsten Schmidt)]

Curious. That should not be! Can you try rebuilding curl and then php5, and then try using curl_version() again?

sudo port -ncuf upgrade curl
sudo port -ncuf upgrade php5

[joe@…]

No luck, I'm afraid:

Maybe there's something weird in your configuration? Try backing up your php.ini, then replacing it with php.ini-recommended which is included in the php5 port.

I'm also not sure about this php5-xdebug. But if that's an extension that you load by adding a line to your php.ini, then trying php.ini-recommended should rule that out as well.

[joe@…]

php5-xdebug is, in fact, an extension loaded by a zend_extension line in php.ini

Unfortunately, running /opt/local/bin/php -r 'print_r(curl_version());' with php.ini-recommended moved to php.ini still produces the bus error.

I'm seeing this same problem on Leopard (10.5.1) with php5 @5.2.5_1 and curl @7.17.1_0. Anything else that might be of use to try to debug this? Where are the logs from the build of a port stored? Maybe php5 can't find curl for some reason. Thanks!

[ryandesign (Ryan Carsten Schmidt)]

Nick, MacPorts stores no logs. You could "sudo port -ncufdv upgrade php5" to see the complete build output. You could send everything to a file with "sudo port -ncufdv upgrade php5 &>php5.log" and then examine php5.log for anything curl-related.

Do either of you have anything in /usr/local/lib? If so, try moving /usr/local aside (rename it to /usr/local-off) and reinstall curl and php5 again.

Or, do either of you have Fink installed? Anything in /sw/lib?

Or, do either of you have DYLD_LIBRARY_PATH or DYLD_FALLBACK_LIBRARY_PATH set?

$ ls /usr/local
ls: /usr/local: No such file or directory

Never installed Fink.

$ ls /sw
ls: /sw: No such file or directory

Or, do either of you have DYLD_LIBRARY_PATH or DYLD_FALLBACK_LIBRARY_PATH set?

$ echo $DYLD_LIBRARY_PATH

$ echo $DYLD_FALLBACK_LIBRARY_PATH

Has this issue of bus errors occuring when both apache2 and curl are in use been resolved? I am experiencing the same problem when running perl scripts. Scripts that include system calls to curl or to lwp-request cause a bus error.

I am running Leopard (10.5.4) on macbook and am using the apache2, curl and lwp-request downloaded from macports.

Another description of this problem is at ​http://webwork.maa.org/moodle/mod/forum/discuss.php?d=6043

I have seen similar reports dating from November 2007 about macports and the (then new ) leopard installation. I have also seen reports from debian builds from earlier years that were fixed by "upgrading to the newest release". Unfortunately I wasn't able to find any details about the fix.

Thank you for your attention.

Take care,

Replying to gage@math.rochester.edu:

I still cannot reproduce this problem on my systems, either with 10.4.11 or 10.5.4. If you can attach a minimal perl script which I can run on my systems to see the problem, I can attempt to look into this further.

[blb@…]

Is anyone still seeing this, I can't reproduce either? If it is still an issue for someone, interesting information would include the output from

otool -L /opt/local/bin/php

and

otool -L /opt/local/lib/libcurl.dylib
