Re: [Valgrind-developers] Fedora14/x64 strncasecmp() problem

[Дмитрий Д. <di...@gm...>]

Ah, i find err. I add patch for strncasecmp, while i need patch for
strcasecmp :)

Now work fine.

REDIR: 0x33d6286790 (strcasecmp) redirected to 0x48015ca (_vgnU_ifunc_wrapper)
REDIR: 0x33d63258d0 (__strcasecmp_sse42) redirected to 0x4a06d00 (strcasecmp)

PR https://bugs.kde.org/show_bug.cgi?id=256600 with patch for
strcasecmp and strncasecmp.

Thank You,
Dmitry
