pahole crashes on 32bit with large number of CPUs #54
Description
TL;DR: -j default should be limited when running on a 32bit platform.
When building an armv7 distribution kernel 'natively' running full 32bit userspace on an arm64 machine with 160 CPU threads pahole reliably crashes when generating BTF for vmlinux. Of course, cross-compiling using 64bit toolchain, using reduced configuration targeted to a specific machine, or manually passing a -j argument are possible workarounds.
However, the default is for pahole to crash.
