It trapped in Fcons (called from Fmapcar), so it could look like a
garbage collector bug, but it's hard to tell (and even harder to
debug).
You reported another trap on July 6, also in Fcons (called via
Fmapatoms). Could be related...
BTW, if emacs traps, please also use the "xbacktrace" command
in gdb to show the lisp call stack.
