>> I haven't upgraded to Lion yet, so I can't easily run this myself, but can you get a backtrace via gdb?  Just run gpg under gdb, and "break malloc_error_break", then "run --card-status".  It'll stop at the breakpoint, and you can then do "bt full".

Werner spotted it earlier.  This looks like a 32-bit/64-bit mismatch between gpg and pcsc.  It's an open bug at
