https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=209907 Bug ID: 209907 Summary: _ascii_wcsnrtombs neglects to set src on EILSEQ error Product: Base System Version: 11.0-CURRENT Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: standards Assignee: freebsd-standards@FreeBSD.org Reporter: roel@abittechnical.com Created attachment 170884 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=170884&action=edit Test program that reproduces the issue I noticed that when using wcsrtombs, if a character is encountered that can not be converted, it sets errno to EILSEQ and returns (size_t)-1. However *src still points to the original character, even though it should point to the character after the one that conversion stopped at. I've attached a test program that reproduces the issue. The expected output is: inptr - in: 7 The actual output is: inptr - in: 0 The culprit appears to be in _ascii_wcsnrtombs, line 181 in lib/libc/locale/ascii.c: it's missing a "*src = s;" statement before the return. -- You are receiving this mail because: You are the assignee for the bug.home | help
