            Bug ID: 262401
           Summary: [FreeBSD 14.0-CURRENT] Signal 11 when compiling i386
           Product: Base System
           Version: CURRENT
          Hardware: i386
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern

Kernel config file used for compilation

During the compilation of GENERIC i386 kernel, I observe random Singal 11
occurrences at different moments of compilation. However, usually it is
possible to compile the kernel after a few retries, but it often fails at some
other point of the compilation.

Example log:
make buildkernel KERNCONF=GENERIC
ld -m elf_i386_fbsd -d -warn-common --build-id=sha1 -T
/usr/src/sys/conf/ldscript.kmod.i386 -r -d  -o acpi_fujitsu.kld acpi_fujitsu.o
*** Signal 11

make[5]: stopped in /usr/src/sys/modules/acpi/acpi_fujitsu
*** Error code 1

make[4]: stopped in /usr/src/sys/modules/acpi
*** Error code 1

make[3]: stopped in /usr/src/sys/modules
*** Error code 1

make[2]: stopped in /usr/obj/usr/src/i386.i386/sys/GENERIC
      952.82 real       898.11 user       122.62 sys
*** Error code 1

make[1]: stopped in /usr/src
*** Error code 1

make: stopped in /usr/src

The issue was observed on 3 machines with same CPU and motherboard type,
therefore damaged RAM, disk or other hardware issue can be ruled out with high
CPU: Cascade Lake, Xeon Type 0, Family 6, Model 85, Stepping 7
Motherboard: S2600WF (WolfPass)

Kernel Sources version:
2022-Mar-03 09:53, REVISION: f266082f113
Also observed on previous src.txz snapshot.
