Assuming that the VC8 there implies this was built with VisualSomething 8.x
then the 'bug' you care about here probably can't be fixed. There is no
guarantee of interoperability between binary object files built by compilers
from different vendors. This is a fairly well documented issue.
It still shouldn't segfault, even when fed 'garbage', but if you want to
chase that, you'll need to generate a full backtrace into where it segfaults
and probably will want to refer to the upstream gcc protocol for reporting
such bugs, so as to provide all the information they would require to debug
and fix that.
If what you care about is linking your app, then you'll want to rebuild
SDL et al. from source using the same compiler - and this isn't really a
bug in this package, just an unfortunate history of lacking the standards
for what you are trying to work.
So assuming again, the latter case, I'm closing this as a bug for us to
track here (since we don't have a general-industry meta-package that I
can reassign it to :). The mingw folk can't fix this, and nor can we.
Sorry,
Ron
