It looks exactly like the issue fixed in > commit 6e21f6f34c1d7c3a7a059062e1ddd9705c984e2c (but I did not cherry-pick > and test that on top of 1.12.3 to test that theory). I added it to stable/1.12 and another patch fixing the initialization of the parameters struct, with Samuel reported to fix the issue upstream (He pinged me in priv too, and I'm helping him to track it). Samuel, Could you please check if the 1.12 stable branch is OK now? Regards, Mauro Thanks, Mauro
