While using clang to compile this code, the output is also 1. This, at a
certain extent, indicates that the problem was caused by the
arm-linux-gnueabic-gcc compiler.

When:
1. removing Line #3 and Line #9, i.e., the { } block
or
2. changing "for(;a<2;)" to "for(;1;)"
or
3. removing Line #4
the result are both correct.

Bug 85202 is another most similar bug with the "continue" statement.
