armv7 main's gpart: signal 11 core dump during boot, before login; xo_format_string_direct; official pkgbase distribution (kernel and world)
Date: Sun, 28 Dec 2025 06:03:06 UTC
Context:
# uname -apKU
FreeBSD OPiP2E-RPi2v1p1 16.0-CURRENT FreeBSD 16.0-CURRENT main-n282732-939ac0c8fde2 GENERIC-NODEBUG arm armv7 1600007 1600007
That is an official pkgbase distribution that I installed, not
a personal build. pkgbase for main has world being a debug
build, no matter which of the kernels one choses to boot.
For pkgbase, 939ac0c8fde2 would be correct(?) for the kernel
but might not be exact for the world: /usr/src/sys/ and
/usr/src/ (without sys/) are from different times, last I
knew anyway. Changes can happen between.
During boot, the time on the Orange Pi Plus 2ed is bad so:
# ls -lodT /gpart.core
-rw------- 1 root wheel nodump 3174400 Jan 1 00:01:01 2010 /gpart.core
Also, for pkgbase, a source file distributed can be newer
for its time stamp than the program distributed that was
based on the source file. Such happens below.
Core was generated by `gpart show'.
Program terminated with signal SIGSEGV, Segmentation fault.
