In the Android app, the payment of CHF 0.23 afterwards showed as pending while the service was down; after relaunching taler-merchant-httpd payment went through, however:

Doing a second payment in the same self-provisioned instance, the issue could be "reliably" reproduced, the core dump happens exactly after the payment is confirmed on the wallet-side; in the taler-merchant-httpd logs it even states that the order was already paid, while the app shows it pending after the crash.

Payment shows done at the URL with the QR code which is visible in the screenshot above (cf. https://bugs.gnunet.org/file_download.php?file_id=1970&type=bug) immediately after restarting taler-merchant-httpd. |
|
|
you should be getting a core dump. Can you gdb it and share the result of (gdb) print *pc (after going up to the TMH_post_orders_ID_pay function)? |
|
|
Never mind, figured it out. |
|
|
Fix committed to master branch. |

Great ty, can be confirmed to work with the newest version of taler-merchant released in trixie-testing, as also shown in today's QC session creating various orders and paying them; also refunds worked:taler-merchant-httpd@bcead3ae4f5e:/var/taler-src/gnunet$ taler-merchant-httpd --version taler-merchant-httpd v1.2.1-git-70957d8 |
