fwiw, this seems to be triggered by ANALYZE.
At least i can trigger it by executing ANALYZE on the table (attached
is a stacktrace of a backend exhibiting the failure)

Another thing is this messages i got when compiling:
"""
mmxlog.c: In function ‘minmax_xlog_revmap_set’:
mmxlog.c:161:14: warning: unused variable ‘blkno’ [-Wunused-variable]

this function [-Wmaybe-uninitialized]
