Since publishing the build with the new toolchain, the identifiable
crashes have been concentrating within / around the LWIP / Wifi
stacks.<br>
<br>
I have now upgraded to the latest toolchain update (<a

<br>
As a new Wifi blob still isn't available, I have also disabled
CONFIG_WIFI_LWIP_ALLOCATION_FROM_SPIRAM_FIRST to see if that helps.<br>
<br>
Internal memory use went up a bit, but totally acceptable. I'm going
to publish the new build to my "edge" users now.<br>

It *is* worth trying, Espressif just forgot to mention a necessary
build config change.<br>

I've created a test branch for this: <a

I'm now running the new version on both my modules, and they seem
to be very stable up to now. Not a single websocket data
corruption yet.<br>
<br>
I'll publish the build to my "edge" users now.<br>

Not worth trying yet.<br>
<br>
It seems the toolchain libstdc++ hasn't been built with
workaround, std::string is still broken.<br>
