[Gluster-devel] Re: [List-hacking] Trampoline warning for dict.c, proto-srv.c:

[Harshavardhana]

Hi all,

    Trampoline problem seems to be a GCC bug which was actually crippling
from gcc-3.4.x series. Was there till gcc-4.0.x, but has been fixed
recently in gcc-4.1.1 and gcc-4.1.2. Same was observed while compiling
linux kernel, for gcc older versions. A Compiler driven bug, so
nothing to worry about :).
