| Summary | 0004486: merchant kill segfaults | ||||
| Description | If the merchant gets a SIGTERM/SIGKILL while at least one /keys request is active, it segfaults. It seems to depend on TALER_EXCHANGE_disconnect(). See the valgrind output attached. | ||||
| Steps To Reproduce | launch the merchant by specifying a bad exchange's URL in the config; after the first /keys request, kill the merchant | ||||
