Hi!
Sorry to say that, but I no longer have access to that machine for
testing this bug :/
At this moment I saw the Bus Error inside QEMU but copying the file
over the device when running it got stuck, with no error message, I had
to ctrl+c it to exit.
With QEMU I was using Ubuntu 9.10, and inside the device there was an
special version of openwrt.
About the -M option I don't remember much of it, I suppose it was mips
or mipsel.
And that's all I can say about that, sorry :(

I can't reproduce this on a Debian testing install within a mipsel
QEMU VM: the current PHP 5.2 and 5.3 SVN branches compile and appear
to work normally, at least for trivial scripts.
So, a few questions:
Are you only seeing the Bus Errors on the actual MIPS devices, or
within QEMU as well?
Are you using a particular Linux distribution?
Which machine type are you emulating with QEMU (ie what -M option, if
any, are you passing to qemu-system-mipsel)?
Have you tried a minimal build without any extensions enabled (ie just
./configure --enable-debug)? Does PHP still Bus Error out in that
case? (If PHP works OK without any extensions, then it would be
incredibly helpful if you were able to narrow down the problem to a
particular extension that causes PHP to crash when it's compiled in.)

Well... not cross compiling. I'm compiling it natively inside a virtual
machine because I can't use the final machine because it lacks memory.

Oh, you're cross-compiling this. We do not support that out-of-box,
you're totally on your own with it.
