In order to verify this theory, I made the following temporary change:
diff --git a/t/chainlint.pl b/t/chainlint.pl
index 556ee91a15..63cac942ac 100755
--- a/t/chainlint.pl
+++ b/t/chainlint.pl
@@ -718,7 +718,7 @@ sub ncores {
# Windows
return $ENV{NUMBER_OF_PROCESSORS} if exists($ENV{NUMBER_OF_PROCESSORS});
# Linux / MSYS2 / Cygwin / WSL
- do { local @ARGV='/proc/cpuinfo'; return scalar(grep(/^processor[\s\d]*:/, <>)); } if -r '/proc/cpuinfo';
+ do { local @ARGV='/proc/cpuinfo'; return scalar(grep(/^processor[\s\d]*:||^CPU[\d]*:/, <>)); } if -r '/proc/cpuinfo';
# macOS & BSD
return qx/sysctl -n hw.ncpu/ if $^O =~ /(?:^darwin$|bsd)/;
return 1;
and I confirm that this fixes the problem.
Let me whip up a patch and post it here.
