I compiled GTK 3.4.0 based on Cairo 1.12.0, after success in complilation, and try to run the GTK3-demo.exe , but the program crashed at once.
Just copied and replaced the libcairo-2.dll with the old version (1.10.2) without any recompilation, the GTK3-DEMO.exe could run correctly at once.
It is clear, the bug result in the Cairo 1.12.0. Usig WinDbg for troubleshooting, the crash is due to any illegal heap operation "HEAP[gtk3-demo.exe]: Heap block at 000000000329B170 modified at 000000000329B3B8 past requested size of 238".

That callstack is garbage. Any change you can improve it with different compile options?
I am using GCC 4.7.0 ( MinGW 64) and executing .Configure after MSYS, both 1.10.2 and 1.12.0 using the same Configure options.
I´m having a similar problem here, unfortunatelly my build was done without the symbol table too. I`ll rebuild everithing with gdb support tonight to see if I can get a better stack trace.
In the meanwhile: Did you try to compile another version of cairo with the same settings? May be an older one?
Ops! My bad! I did notice the last comment.

The problem is not happening again using the latest 64 bits binaries for MinGW & gtk3 got from OpenSUSE build service.
PS: I can´t pinpoint in what version the problem stopped.
