After using poudriere to build ports for native cortex-a72
on the MACCHIATObin Double Shot (and similarly for
cortex-a57 on the OverDrive 1000) I attempted to do my
usual bulk build targeting cortex-a7 via poudriere-devel:
# poudriere jail -i -jFBSDFSSDjailArmV7
Jail name: FBSDFSSDjailArmV7
Jail version: 14.0-CURRENT
Jail arch: arm.armv7
Jail method: null
Jail mount: /usr/obj/DESTDIRs/clang-armv7-installworld-poud
Jail fs: =20
Jail updated: 2021-01-27 14:47:10
Jail pkgbase: disabled
But I got some SIGSEGV failures that I've never before
had analogous failures. I'll show the 6 backtraces.
They all have a similar type-of-context but in various
programs, summarized as (from the lldb bt outputs):
gmake`new_job(file=3D<unavailable>) [3 examples]
and:
sh`waitcmdloop(job=3D0x00064230) [2 examples]
and:
cmake`(anonymous namespace)::RunCommand(command=3D<unavailable>, =
output=3D"14.0-CURRENT\n", retVal=3D<unavailable>, dir=3D<unavailable>, =
verbose=3D<unavailable>, encoding=3DAuto)
(Only 83 ports built of 208 built, 5 failed, and 120 were
skipped.)
I have not yet tried simply running poudriere again to see
how reliable the specific failures may or may not be: I'm
first collecting and reporting this information. Nor have
I tried doing the build on the cortex-a57 context instead.
I'll note that when I looked at detail as the assembler level
it appeared that there was a frame not shown between #0 and #1
in lldb's output: Frame #1 "->" was indicating the instruction
after a simple bl to a not-shown subroutine.

It was basically the same list of ports that had built for
the cortex-a72 target context (208 armv7/cortex-a7 vs. 209
cortex-a72). I've no evidence of native aarch64 problems.
The cortex-a57 self built its 209 just fine and so far the
a57's cortex-a53 targeted build of the 209 has had no
problems (built 148 with 61 yet to finish).
So the problem seems to be specific armv7 activity on aarch64
systems, or possibly on cortex-a72 specifically.
For reference . . .
