is there any issue with installing the compat-gcc34 package from centos 6 on centos 7 ?

probably won't work at all, as its dependencies are very likely to be all wrong.

compat packages in RHEL/CentOS are designed to go back one major release. So, compat-gcc34 on EL6 was designed for EL5 compatibility. on EL7, there's a compat-gcc-44 to provide EL6 compatibility.

I suggest you recompile whatever software depends on gcc 3.4 to run with el7's native gcc 4.8
