Crash in typescript using nodejs 16 on ppcle #38521
Description
- Version: 16.0.0
- Platform: Linux ls-ub-lf40a2dv 4.4.0-200-generic doc: update AUTHORS file, add tool for doing it #232-Ubuntu SMP Wed Jan 13 10:17:10 UTC 2021 ppc64le ppc64le ppc64le GNU/Linux
- Subsystem: @nodejs/v8
What steps will reproduce the bug?
building a project (unfortunately closed source) using typescript 4.2.4
Update: Seems to happen with other projects, e.g. building typescript itself
How often does it reproduce? Is there a required condition?
always, no special condition besides using PPCLE (no problem on windows, linux x86, linux arm).
What is the expected behavior?
building works also on PPCLE
What do you see instead?

Additional information
If I attach the debugger problem is gone.
If I add typeof(node.slice) (which should be a not in my opinion) just before the line causing the TypeError it no longer occurs but a similar TypeError happens at another place.
If I add also typeof() checks at the next two such locations I finally end up in a segmentation fault with a quite small callstack:
#0 0x00000000115dd9b4 in Builtins_LoadIC_Megamorphic ()
#1 0x00000e8ec1d600e0 in ?? ()
