Everyone please have a look at…
https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/issues/189#issuecomment-457334248
Please try to reproduce the bug on your modules.
I'm open for explanations.
I thought this might be some copy-on-write bug with std::string, but
the gcc 5.x libstdc++ does no longer use that implementation
(wouldn't be C++11 compliant as well). I also tried moving all
strings to temporary buffers, but modes 5 & 6 eliminated this
explanation as well.
My remaining theories:
- A task writing out of bounds (but only 0-bytes?)
- A hardware issue only affecting some modules
A hardware issue only affecting some percentage of ESP32 could
explain this as well as the strange heap corruptions that seem to
affect some modules especially often.
Regards,
Michael
