The retrace is incomplete for some reason, but the missing frames are:
#7 grub_disk_read #8 grub_fat_read_data #9 grub_fat_read #10 grub_file_read
I'm not sure how illuminating that will be by itself, since it's malloc arena corruption so the symptom will probably be distant from the cause. I think this needs to be reproduced under valgrind somehow.
