------- Comment #17 from rleigh at debian dot org 2006-06-16 16:59 ------- Created an attachment (id=11682) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=11682&action=view) Use mbsnrtowcs directly.
This testcase is similar to the original, with the exception that it uses mbsnrtowcs in place of the codecvt locale facet. It also initialises the locale with setlocale() for LC_CTYPE. It shows some interesting results, in fact the exact opposite of the original testcase: GCC ver powerpc i386 3.3 fail fail 3.4 OK OK 4.0 OK fail 4.1 OK fail 4.2 OK fail With this test, the expected output is this: $ ./wide2 1 fffäß» fffäß» The output for the failed tests: GCC 3.3: powerpc (GCC 3.3 was bad at wide streams; the output is "lost"): $ ./wide2 1 fffäß» i386: $ ./wide2 wide2: ../iconv/loop.c:425: utf8_internal_loop_single: Assertion `inptr - bytebuf > (state->__count & 7)' failed. Aborted GCC 4.0/i386: $ ./wide2 wide2: ../iconv/loop.c:425: utf8_internal_loop_single: Assertion `inptr - bytebuf > (state->__count & 7)' failed. Aborted GCC 4.1/i386: ./wide2 wide2: ../iconv/loop.c:425: utf8_internal_loop_single: Assertion `inptr - bytebuf > (state->__count & 7)' failed. Aborted GCC 4.2/i386: $ ./wide2 wide2: ../iconv/loop.c:425: utf8_internal_loop_single: Assertion `inptr - bytebuf > (state->__count & 7)' failed. Aborted Please do allow for the fact that one (or both) of these testcases might be buggy; I've never used these interfaces before. However... the behaviour is still highly variable between the two platforms. Regards, Roger -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28059
