testing this repo on Android 10 / termux fails: 'Cannot resolve caller p6_to_p5'

[stuart-little]

I am trying to install on Android 10 with the Termux terminal emulator. zef install Inline::Perl5 works just fine, including tests. Nevertheless, if I

• clone this repo,
• cd into it, and
• run zef install .

I get a number of warnings on building (which does eventually succeed) followed by eventual failure during testing.

The full build/text/fail-to-install log is here. Some highlights are that

• building results in a number of -Wunused-function warnings (e.g.

/data/data/com.termux/files/usr/lib/perl5/5.32.0/aarch64-android/CORE/op_reg_common.h:65:1: warning: unused function 'set_regex_charset'

• testing fails on trying to invoke p6_to_p5:

[Inline::Perl5] Cannot resolve caller p6_to_p5(Inline::Perl5.new: (Mu)); none of these signatures match:

Additional info:

I have tried the same procedure (clone, cd, zef install .) on three x86_64 Linux systems with no issue, so this is specific to Android (or maybe rather aarch64).
