Trying to run npm on aarch64 raspberry pi 3, I'm running into a
reliable asm-related crash with pretty much any use:
------
$ mkdir test
$ cd test
$ npm init
This utility will walk you through creating a package.json file.
[...]
Press ^C at any time to quit.
package name: (test) Segmentation fault (core dumped)
------
I ran into it on 7.6 and updated to -current with no change.
Looking for a simpler reproducer I ran through "eopenssl33 speed"
and I hit the same backtrace with "eopenssl33 speed rand".
Also tried openssl 3.4 and see the same.
It's a pretty weedy machine as far as crypto blocks are concerned,
"cpu0: CRC32,ASID16".
This doesn't happen on Apple M2.
Any ideas please? Happy to do more focused tests to narrow it down
further if there's anything that would be useful. The contents of
registers referenced in the ldr look aligned. I'm not much good
at debugging asm though.

(Tried running directly under gdb, e.g. 'egdb -q -ex run --args
eopenssl33 speed rand', to see if I'd get a better stack trace,
but it doesn't go well because it runs into SIGILLs from the
CPU feature detection code).
