This is a bug report for perl from dueffert@uwe-dueffert.de, generated with the help of perlbug 1.42 running under perl 5.37.1. ----------------------------------------------------------------- perl-5.37.1 breaks texinfo-6.8. The error occurring is "Unexpected character in locale name 'XY at ../tp/Texinfo/Report.pm line 320." with XY being random. This breaks texinfo build and later on on a system using it, it e.g. breaks building binutils-2.38 too. Under exactly same conditions (same machine, environment, build instructions), there is no problem with perl-5.37.0 (or earlier). You can even switch back and forth: Build and install perl-5.37.0 (or earlier) and building texinfo+binutils works fine, build and install perl-5.37.1 and building texinfo+binutils fails with above error. Repeatably. This is a Linux From Scratch system. I can surely provide more info if you ask for some. ----------------------------------------------------------------- --- Flags: category=core severity=high --- Site configuration information for perl 5.37.1: Configured by root at Sat Jul 2 12:56:52 CEST 2022.
