Bug ID: 58628
Summary: Incorrect std::isalpha results with UTF-8 locale on
illumos
Product: gcc
Version: 4.4.7
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: alp at rsu dot ru
The following example when compiled with gcc 3.4,4.7 or 4.4 and launched with
en_US.UTF-8 locale on illumos says that char with 196 code is alphabetic,
however it's not a correct UTF-8 symbol.
$ env LANG=en_US.UTF-8 ./test_ctype
"�"
letter is �
(int)letter is 196
std::use_facet:true
If this program is compiled with Sun Studio Compiler (CC) results are:
$ env LANG=en_US.UTF-8 ./test_ctype_CC
"�"
letter is �
(int)letter is 196
std::use_facet:false
if I compile this program on Linux / FreeBSD , results are correct.
