## Every body folds into one, so __text holds a single 6-byte body plus _main
## rather than the 3 MiB (0x30000d) the unfolded copies occupy.
# SECT: Idx Name Size
# SECT-NEXT: 0 __text 00000009
## The sentinels bracket the group, so checking that the first and last members
## of the class share an address covers the whole run of folds.
