pgloader fails to build with SBCL 1.4.11 (regression)

[Sébastien Villemot]

On x86_64, trying to build pgloader with SBCL 1.4.11 results in the following failure:

buildapp --require sb-posix \
 --require sb-bsd-sockets \
 --load /usr/share/common-lisp/source/cl-asdf/build/asdf.lisp \
 --asdf-path . \
 --asdf-tree /usr/share/common-lisp/systems \

 --load-system asdf-system-connections \
 --load-system pgloader \
 --load src/hooks.lisp \
 --entry pgloader:main \

Note that this is a regression, the problem was not present in SBCL 1.4.10.

The bug has been reported on different platforms:

it's a bug in the project called nibbles. it was using SBCL's internal API, and unsurprisingly it broke at a random point in time. it has been fixed in nibbles already:
