Everyone please have a look at…<br>

<br>
Please try to reproduce the bug on your modules.<br>
<br>
I'm open for explanations.<br>
<br>
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.<br>
<br>
My remaining theories:<br>
<ul>
<li>A task writing out of bounds (but only 0-bytes?)</li>
<li>A hardware issue only affecting some modules<br>
</li>
</ul>
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.<br>
<br>
