Running it with strace produced this near the end:
open("/packages/local/share/man/index.db", O_RDONLY) = 3
fstat64(3, {st_mode=S_IFREG|0644, st_size=3208201, ...}) = 0
fcntl64(3, F_SETLK, {type=F_RDLCK, whence=SEEK_SET, start=0, len=0}) = 0
read(3,
"\316\232W\23\0\0\20\0\0\0\20\0\0\0\0\0\0\0\20\0\21\0\0\0\0\0\20\0\246\252\0\0"...,

mmap2(NULL, 1052672, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0xb72b7000
read(3,
"\0\0\0\0\5\0\0\0\0\0\0\0\253\0300\0\0\0\0\0\17\0\0\0\0\0\0\0003\2370\0"...,
1048524) = 1048524
lseek(3, 1048576, SEEK_SET) = 1048576
read(3, "", 0) = 0
lseek(3, 3078034552, SEEK_SET) = -1 EINVAL (Invalid argument)
write(2, "gdbm fatal: ", 12gdbm fatal: ) = 12
The file it read is nowhere near as big as the lssek(3, 3078034552, SEEK_SET)
tried to position, and it should know that from the fstat64() call just above!
The file is:
$ ls -l /packages/local/share/man/index.db
-rw-r--r-- 1 man daemon 3208201 Nov 30 10:15 /packages/local/share/man/index.db
I don't know why it attempted to go that far, presumably it is reading
an offset from the database and that is now wrong?
