Bug ID: 112529 Summary: ACATS test c250002 uses illegal filename on APFS filesystem Product: gcc Version: 14.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: testsuite Assignee: unassigned at gcc dot gnu.org Reporter: simon at pushface dot org Target Milestone: --- This test checks that characters in Latin-1 above ASCII.Del can be used in identifiers, character literals and strings. Some of the identifiers are package names, so when the source is "gnatchopped' they become filenames. In Apple's HFS+, although filesystem naming is UTF-8 (well, Apple's version), attempts to create files with Latin-1 names are allowed by silent name conversion: for example, given the filename c250002_รก.ads, what is stored is c250002_%E1.ads. In Apple's current APFS, however, this attempt results in failure: $ gnatchop c250002.aw splitting c250002.aw into: c250002_0.ads cannot create c250002_?.ads cannot create c250002_?.adb c250002.adb It would perhaps be ideal to report this test as 'unsupported' if run on macOS, but this could be challenging given the rather ad-hoc nature of the scripts involved. Just not running the test at all wouldn't be right, since it runs OK on other operating systems.
