Description:
------------
Code compiled from other machines gives:

segfault at 185148e0 ip 082f1241 sp bf939ca0 error 4  

The vm?s are on diferent servers (Quad core) and Xeon quad.
Linux debian and the same configuration.(x32)

Can that be the cause?

Reproduce code:
---------------
any code

Expected result:
----------------
file contents

Actual result:

Does the bcompiler generated code works on diferent computers beside the pc where was generated ?

Is not this a normal question ?
 [2010-11-10 18:30 UTC] alan at akbkhome dot com
yes, bytecodes compiled on one machine should run others,

anything resulting in a segfault needs investigating

Without a backtrace nothing can be done to help you.

Do you know if Quad core and Xeon quad systems are both 32-bit or 64-bit, or they have different architectures? In the last case bytecodes generated on one system won't work on the other.

Is all the same arquitecture. The problem is in bcompiler.

The code works in the same machine,and even there sometimes i get errors,the working code sometimes fails.

Debuging is a pain.

This code is like any other open-source, doenst work without heavy "tweaking".

use uname -a to find out if you are running 64bit or 32bit 
linux. - the cpu architecture is not really relivant. (you 
can run 32bit linux on a 64bit cpu)

without backtraces it's not possible to debug this.
