Presumably it is useful on some other systems as well. If it is deemed a potential 'untrusted' location, it should at least be acceptable to do it conditionally on running on FreeBSD.

I'm experiencing strange behavior from CCL on Linux x86. When invoking it in the normal way (ccl/scripts/ccl) as well as directly (./lx86cl lx86cl.image) I receive no output from the application. It does not respond to C-c or C-d, nor can I execute any Lisp forms.

Notes from openmcl-devel, R. Matthew Emerson:

"I tried to run the lisp on an EC2 image myself.

What seems to happen is that the lisp kernel starts up, maps in the heap image, and starts running lisp code, which pretty much immediately tries to allocate memory by taking a trap (int $0xc5 on x86 systems).

For some reason, instead of generating a SIGSEGV like we expect, the system just sort of sits there, dumbly staring at the alloc_trap in a puzzled manner.

I don't know if this a symptom of running on Xen or whether there is some other peculiarity of Amazon's EC2 set-up. I have run Clozure CL on a a Linux Xen instance before, though it was a 64-bit version."

Error message:

"? Can't determine state of thread 0x147a50, interrupted during memory allocation ? for help [672] Clozure CL kernel debugger: "

I am able to fairly consistently enter the kernel debugger by re- loading my current ASDF system (a multi-threaded web server app) and reading ~150MB data from disk into a bunch of vectors. This is done within a SLIME session.

This issue did not seem to come up when running CCL (1.4 and trunk) under 10.5.
