Title:
bash 5.2 regression too-aggressive optimizing of forks in an `eval'
command inside a (command) subshell
Status in bash package in Ubuntu:
Fix Released
Status in ovn package in Ubuntu:
Fix Released
Bug description:
OVN makes use of GNU autotest for its testsuite. This in turn is a
heavy user of bash.
For some reason, when the 'ovn-controller incremental processing' test
is executed using bash 5.2 on Debian experimental or Ubuntu
Kinetic/Lunar, the `eval` [0] in the `counter_delta_` function
misinterprets successful execution of commands [1], leading to a false
negative for the 'ovn-controller incremental processing' test [2].
Backporting the bash 5.1 package from Jammy, or compiling bash 5.1
from upstream sources and rerunning the test makes it succeed.
This does come across as a regression in bash.
