At first, I applied the patch to my previous build tree and reran make and make check in libstdc++, but the failures persisted. To make sure there wasn't any missing dependency, I removed the libstdc++-v3 directory, reconfigure and rebuilt, but with the same results. I happened to build on Tru64 UNIX from the same sources, and see lots of wchar_t failures there, too. Rainer

Badabing. I'm planning to add isblank to std::locale (LWG 2019) which will need changes to all the locale models so while I'm doing that I will overhaul the ieee locale model (possibly adding a POSIX 2008 version as well, which would be close to the gnu model) and I'll also address this, so we can handle values over (1<<15). Currently that '15' maximum is hardcoded in a few places.

Are you using a specific configure value for --enable-clocale or just using the
default "generic" model?
What about this test, I assume the assertion fails:
#include
#include
int main()
{
struct ctype : std::ctype
{
bool test()
{
return this->is(std::ctype_base::space, L' ');
}
} c;
assert( c.test() == iswctype(L' ', wctype("space")) );
}
What is the value of _ISspace in /usr/include/ctype.h ?
If it's greater than (1<<15) that would explain it

I wonder if the fact that char is unsigned on IRIX might have something to do with this? OTOH, compiling them with -fsigned-char doesn't change anything. If I compile the tests with SGI CC instead, they do return 1. Rainer

Here's a simpler test, which should return 1:
#include
int main()
{
return isspace(L' ', std::locale());
}
if that works, how about this, which should also return 1:
#include
#include
#include
int main()
{
std::wstring s(L" ");
std::wistringstream ss;
return isspace(s[0], ss.getloc());
}

extracting str10 doesn't seem to have stopped at the first whitespace
character, implying a problem with the wchar_t equivalent of iswspace
