I'm seeing a testsuite regression on 3.4 and mainline when running with extra
flags -fpic or -fPIC. The testcase does use ebx, however 3.3 manages to pass
so somehow it can work and this is a regression. (The testcase is identical in
all three branches.)

I get this in the log file:

These should be just skiped with -fPIC.

Is it a bug that 3.3 compiles it without a problem?

Yes see PR 14128 for which it shows why this error was added.
