SIGSEGV: segmentation violation when activating mqtt #17067

Closed juergen-weber closed 3 weeks ago

juergen-weber commented 3 weeks ago

Describe the bug

evcc worked fine with version 0.131.0. Version 0.131.4 stops with a segmentation violation - even with a fresh clone (git clone https://github.com/evcc-io/evcc). Issue seems to be related to the mqtt module. With mqtt being disabled, evcc starts up. Compiled on: EL9 5.14.0-427.42.1.el9_4.x86_64 go version go1.23.2 linux/amd64 node: '22.10.0'

Steps to reproduce

  1. git clone https://github.com/evcc-io/evcc
  2. make
  3. ./evcc

  4. ...
