The following causes the assertion too, using gcc 4.7.2:
% gcc -std=c99 float.c -o float-linux-c99
% ./float-linux-c99
float-linux-c99: float.c:3: main: Assertion `12345.6789f == getfloat()' failed.
It seems this bug is not specific to gcc-mingw32, but is either really
a bug in gcc or expected behaviour in C99 (I don't know which).
Incidentally, since you're running unstable, you can use the
i686-w64-mingw32 triplet instead of i586-mingw32msvc; the latter will
be going away at some point...
Regards,
Stephen
