[Maria-developers] what compiler should i use when building mariadb?

hello, we have been using gcc 4.4 to build mysql and mariadb successfully. however, when we tried to use gcc 4.7.1 to build mariadb-5.5.25, we hit this problem: /home/tokubuild/build-tokudb-46462/mariadb-5.5.25-tokudb-46462-linux-x86_64-build/mariadb-5.5.25-tokudb-46462-src/mysys/my_context.c: Assembler messages: /home/tokubuild/build-tokudb-46462/mariadb-5.5.25-tokudb-46462-linux-x86_64-build/mariadb-5.5.25-tokudb-46462-src/mysys/my_context.c:207: Error: CFI instruction used without previous .cfi_startproc what compiler do you use to build mariadb? thanks rich prohaska
