Description:
------------
I installed bcompiler on my CentOS 5 machine and Mac OS X 
10.6 machine yesterday. They can't run one another's 
compiled files because the different bytecode versions 
installed. There's nothing in the documentation that 
addresses this issue (and possibly how to fix it).

Additionally, is there a way to force the compiler to use a 
certain (older) version?


CentOS 5.5, PHP 5.2.10, Apache 2.2.3, x86_64
----
bcompiler version	0.9.3-devs
current bytecode version	0.21
can parse bytecode version	0.7, 0.9, 0.11, 0.12, 0.14, 
0.18, 0.21



Mac OS X 10.6, PHP 5.3.3, Apache 2.2.15, i386
----
bcompiler version	0.9.3-devs
current bytecode version	0.22
can parse bytecode version	0.20, 0.22

This sounds partly correct

PHP5.3 will produce bytecodes that are not compatible with 
other versions. due to the extra features in the lanuguage

Val might know 5.3/0.9.3-dev can not read older bytecodes 
though.

Thank you for taking the time to write to us, but this is not
a bug.

Right, bcompiled code is typically incompatible between PHP versions due to changes in Zend engine internals. So you can only run a bytecode with the same PHP version that was used to compile it.
