No, it isn't necessarily related to that package, because the problem
happened during GC.  Your package just happened to trigger GC.

Can you try typing the following command definition, and then running
the command?  When you run it, does GDB also hang indefinitely?

  (gdb) define count-markers
   > set $count = 0
   > set $markers = BUF_MARKERS(b)
   > while $markers != 0
    > set $count = $count + 1
    > print $count
    > set $markers = $markers->next
    > end
   > end
  (gdb) count-markers
