    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

error log

There are a lot of failures, huge error log attached.

For me it looks like the root cause is the following:

libstdc++-v3/include/bits/basic_string.h:2971:22: note:   mismatched types
'std::size_t {aka long long unsigned int}' and 'const wchar_t*'

That causes for example
error: no matching function for call to '__to_xstring(int (*)(wchar_t*, const
wchar_t*, char*), long long unsigned int, const wchar_t [3], unsigned int&)'

an leads to template argument deduction/substitution failed.

This implies the type of std::vswprintf is wrong on that platform.

Ah of course, this is the fix for PR 52015

You need to use at least r5437 from the Mingw-w64 trunk for 4.8, I will update
the release notes today

(as a note, appears mingw-w64 2.0.8 is not sufficient you need something
newer...)

It should be. 2.0.8 is from r5746 which is new enough.

Yeah I was getting the same error message with 2.0.8 and pinged them about it. 
Apparently the crt they bundled with 2.0.8 wasn't new enough or something like
that, and they plan on releasing a new release soon...from what I could glean
that is.
