Description:
------------
I've installed bcompiler .7 using PECL on FreeBSD. I've
written a script to compile all of my PHP code into
separate files.. either based off of the original file, or
alternatively compiled a class into it's own file. In
order to load the compiled code, I simple have a
include_once in an __autoload, which loads the correct
file.
When I compile the original file, I receive a Segmentation
Fault. When I compile the classes, I receive a Bus Error.
Here's my configure line:
./configure --with-apache=../apache_1.3.33/ --with-mysql
--with-gd --enable-sockets
--with-png-dir=/usr/include/libpng
--with-zlib-dir=/usr/include
--with-jpeg-dir=/usr/include/libjpeg --with-mhash
--with-pdflib --disable-ipv6 --with-dom --with-openssl
Reproduce code:
---------------
Here's the class compiler excerpt:
$fh = fopen("/usr/www/compiled/" . $out . ".class.phpb", "w");
bcompiler_write_header($fh);
bcompiler_write_class($fh, $out);
bcompiler_write_footer($fh);
fclose($fh);
And to load, I tried both:
$fh = fopen("/usr/www/compiled/" . $file,"r");
bcompiler_read($fh);
fclose($fh);
And:
include_once($file);
Actual result:
--------------
Here's the BUS ERROR:

A couple of things... sorry, this comment will be messy. If you would like me to email anything, please ask. I stopped using bcompiler_write_class, because it wouldn't work.. and used _write_file. That's how I got it to work.. I installed the CVS, and first tried to get it to work with 5.0.4. It didn't... Here's a udiff that gets it to compile: --- bcompiler.c.orig Tue Feb 7 15:07:59 2006 +++ bcompiler.c Tue Feb 7 15:10:10 2006 @@ -2807,7 +2807,11 @@ /* new for 0.12 */ if (BCOMPILERG(current_write) >= 0x000c) { BCOMPILER_DEBUG(("-----------------------------\nDEFAULT STATIC MEMBERS:\n")); +#ifdef ZEND_ENGINE_2_1 apc_serialize_hashtable(&zce->default_static_members, apc_serialize_zval_ptr TSRMLS_CC); +#else + apc_serialize_hashtable(&zce->static_members, apc_serialize_zval_ptr TSRMLS_CC); +#endif } /* not sure if statics should be dumped...

I had to recompile the PHP files with bcompiler, however, but then it worked fine. I'll let you close this out, in case there's any more testing you would like me to do.
