[Bug inline-asm/19275] New: [3.4/4.0 regression] gcc.dg/20020919-1.c fails with -fpic/-fPIC on i686-pc-linux-gnu

[ghazi at gcc dot gnu dot org]

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:
