To do that, run "gdb /the/path/to/gpg" then enter "break malloc_error_break", and finally "run --status-fd 1 --card-status".  When you get a prompt, enter "bt full".  Send the output of the bt full.

Dear David,

I have posted the full report from that at the end of this email.

I'm having a (possibly related?) problem with that reader, which is
that it frequently refuses to read the card at all.  At first I
thought the card was not seated properly, but I've concluded that it
is.  Sometimes the reader works flawlessly, and sometimes gpg reports
that the card is not present.  The error only occurs if the reader has
been removed and then reattached.  I have not been able to work out
conditions under which it works and fails.  Do you have any
suggestions for how to go about tracking down the problem?

Best wishes,

Nicholas
