This looks like your build system fails to detect file changes and links outdated .o file(s), or library, which causes a mismatch between your debug info and the real location of the variables. This leads the debugger to look in the wrong place and hence can't read the memory. By inserting the variable int x, Mat a is then again on the stack frame where it's supposed to be according to the debug info. That's my guess anyways.
When I encounter a problem like this I do a 'clean all' followed by a full rebuild of both, the lib and the program using it.
