Manjaro Linux couldn't get thinkfan working

[viper2035]

Hello everyone,
I just started with using Manjaro Linux on my T430S. I used different other Linux distributions before mostly debian based. Now I tried to get thinkfan working on Manjaro Linux. I followed this guide. But at the point of using the command thinkfan -n i got the message:

/usr/include/c++/11.1.0/bits/stl_vector.h:1063: std::vector<_Tp, _Alloc>::const_reference std::vector<_Tp, _Alloc>::operator[](std::vector<_Tp, _Alloc>::size_type) const [with _Tp = int; _Alloc = std::allocator<int>; std::vector<_Tp, _Alloc>::const_reference = const int&; std::vector<_Tp, _Alloc>::size_type = long unsigned int]: Assertion '__n < this->size()' failed.

If I enable the service of thinkfan I got the error message after using systemctl status thinkfan.service:

× thinkfan.service - simple and lightweight fan control program

But I have no glue whats the problem here. My thinkfan.conf isn't that long:

sensors:
  - tpacpi: /proc/acpi/ibm/thermal
    indices: [1]

fans:
  - tpacpi: /proc/acpi/ibm/fan
levels:
  - ["level 0", 0, 70]
  - ["level 1", 65, 73]
  - ["level 3", 70, 80]
  - ["level 5", 75, 88]
  - ["level auto", 83, 255]

Using the commands to read the temperature and fan speed works fines (cat /proc/acpi/ibm/thermal cat /proc/acpi/ibm/fan). And I can set the fan speed by using echo level 1 > /proc/acpi/ibm/fan.
Does anybody got an idea what I did wrong?

Thank you all

This seems to be the same problem as in #139, which should be fixed in the current master branch. It'd be very helpful if you could test with that and report back whether it helps.

Closing for lack of feedback and since the symptoms match fixed & released #139.
