For targets\nthat define alpha as lower|upper (rather than having a distinct bit for\nalpha) this bug meant that all masks which have lower or upper bits set\nwere replaced with alpha when the icase parameter is true. This has the\neffect that trying to do a case insensitive match for [:alnum:],\n[:graph:], or [:print:] was equivalent to matching [:alpha:] instead,\nwhich is obviously not correct.\n\nBased on inspection of the ctype_base.h files under the config/os\ndirectory, the bug appears to affect newlib, picolibc, qnx and vxworks.\n\nlibstdc++-v3/ChangeLog:\n\n\tPR libstdc++/124015\n\t* include/bits/regex.tcc (regex_traits::lookup_classname): Fix\n\thandling of icase parameter.\n---\n\nThis and patch 1/3 are suitable for backport to release branches.\n\nTested x86_64-linux.\n\n libstdc++-v3/include/bits/regex.tcc | 4 ++--\n 1 file changed, 2 insertions(+), 2 deletions(-)", "diff": "diff --git a/libstdc++-v3/include/bits/regex.tcc b/libstdc++-v3/include/bits/regex.tcc\nindex 061b60042eca..71eadd20bfdb 100644\n--- a/libstdc++-v3/include/bits/regex.tcc\n+++ b/libstdc++-v3/include/bits/regex.tcc\n@@ -309,8 +309,8 @@ namespace __detail\n \tif (__s == __it.first)\n \t {\n \t if (__icase\n-\t\t&& ((__it.second\n-\t\t & (ctype_base::lower | ctype_base::upper)) != 0))\n+\t\t&& (__it.second._M_base == ctype_base::lower\n+\t\t || __it.second._M_base == ctype_base::upper))\n \t return ctype_base::alpha;\n \t return __it.second;\n \t }\n", "prefixes": [ "2/3" ] }
