Public bug reported:
When removing a key from a tkrzw hash database, the operation appears to
succeed, but the key is left there with a tombstone style value. This is
present on Ubuntu 25.10 (tkrzw version 1.0.32). The bug disappears when
the package is rebuilt with optimizations disabled (--disable-opt /
-O0). The bug also disappears if simply downloading the upstream source
and building it with `./configure && make`.
Steps to Reproduce:
sudo apt install -y tkrzw-utils
tkrzw_dbm_util create db.hash
tkrzw_dbm_util set db.hash a 1
tkrzw_dbm_util set db.hash b 2
tkrzw_dbm_util set db.hash c 3
tkrzw_dbm_util remove db.hash a
# The following line should NOT contain 'a'
tkrzw_dbm_util list db.hash | sort | cat -A
Expected Results:
b^I2$
c^I3$
Actual Results:
a^I M-^M-- $
b^I2$
c^I3$
