I think that according to this - https://linux.die.net/man/3/confstr - we
have a bug in this code:
size_t confstr(int name, char* buf, size_t len)
{
char tmp[1];
if (!buf) {
buf = tmp;
len = 1;
}
auto set = [=] (const char* v) { return snprintf(buf, len, "%s", v); };
switch (name) {
case _CS_GNU_LIBC_VERSION: return set("glibc 2.16");
case _CS_GNU_LIBPTHREAD_VERSION: return set("NPTL 2.16");
}
debug(fmt("confstr: unknown parameter %1%\n") % name);
abort();
}
We should be returning the length + 1 to allow for the '\0' terminating
character. This breaks newer version of Python 3.
