Hi Gongfa,

Thank you for quick response. I compile the base with your patch just

now. But the error messages are same, the details see below.

*)':

../iocsh.cpp:158: Internal compiler error in `expand_expr', at expr.c:5996

Please post line 158 of that patched iocsh.cpp file so I can be sure

what line that the compiler is complaining about in that message.

There are many other places in Base where that exact same code construct

is used (although the others may all be in C rather than C++ source) —

we're trying to understand why the error is only occurring here.

Wind River have released a number of patches to their GNU compilers

since Tornado 2.2.1 came out, and I wonder whether they've released one

that solves this problem.
