I wasn't suggesting taking the pre-compiled binaries from that site,
but rather for you to use his solution as an example for compiling
There actually might be working VS build files in the main glib source
- you might want to check that too.

It surely is caused by the mixing of the different C Runtimes between
the VS versions - you can't mix handles from different C Runtimes.
I think it's asking for trouble to go down the path that you're
suggesting. It shouldn't be all that complicated to compile glib and
use the real fix.
