#1356 deref of &placed_variable

[Anonymous]

SDCC : mcs51 2.7.2 # (Jun 28 2007) (UNIX)
svn #4870

the following short piece of code produces an
internal compiler error.

--------------------------------------

xdata at 0x1234 char bar;

void foo() {
*(char volatile xdata *) &bar = 0x80;
}

---------------------------------------

without at, no error is generated
without volatile, no error is generated
with cast to *unsigned* char, no error is generated,
but the resulting asm code doesnt do anything,
(just "ret")

the actual error message is

Internal error: validateOpType failed in OP_SYMBOL(IC_RESULT (ic)) @ SDCCcse.c:2172: expected symbol, got value
