In quite a few instances the make log file contains a note such as
*** Error code 254
[number varies, websearch found nothing]

and the error message indicates
cc: error: clang frontend command failed due to signal (use -v to see invocation)

If somebody could tell me how to invoke the -v option I'll try it.
IIRC putting CFLAGS=-v on the command line to make didn't work.

Is there any possibility this is a hardware issue, perhaps with the
microSD card? It's a Samsung EVO Plus, 128GB. No console errors at all,
the troubles appeared several buildworld cycles after starting to use it. 
Single thread make in single-user mode didn't avert the problem,  

Thanks for reading,
