Hmmmm. Any chance you could run the generator in a gdb and check where
this happens?
Use something like this:
rm -rf /tmp/gpt-test ; mkdir /tmp/gpt-test ; gdb --args
/usr/lib/systemd/system-generators/systemd-gpt-auto-generator /tmp/gpt-test
/tmp/gpt-test /tmp/gpt-test
And then set a breakpoint to log_oom():
b log_oom
And then run it:
r
This should then run an break where the incorrect OOM happens. Then, get
me a backtracke please:
bt full
Thanks!
