Hi Alan,
The CellML API is built against the MingW binaries available from
mingw.org rather than any patched version.
$ md5sum /cygdrive/c/MinGW/bin/libstdc++-6.dll
d575f00fbf32f16de1e082e5966f5abc */cygdrive/c/MinGW/bin/libstdc++-6.dll
$ objdump -p /cygdrive/c/MinGW/bin/libstdc++-6.dll |grep
ZNKSt9exception4whatEv
[ 694] _ZNKSt9exception4whatEv
$ /cygdrive/c/MinGW/bin/gcc --version
gcc.exe (GCC) 4.5.2

It looks like that symbol is not new; I suspect that your compiler
version might have a different exception handling mechanism, so an
incompatible C++ ABI. There are two ways of handling exceptions on
Windows: DWARF2, which the version of MingW that the CellML API is build
with uses, and the slower way that doesn't work across DLL boundaries
using setjmp/longjmp (SJLJ exceptions).
However, it looks like recent versions of QtCreator are supposed to be
using dw2 and not sjlj. Do you have an old version of QtCreator by any
chance?
Could you please run objdump -p on your libstdc++-6.dll and grep for
9exception4what?
Best wishes,
Andrew
