I've reduced the testcase by hand:

struct kernel_symbol {
unsigned long value;
};
unsigned long loops_per_jiffy = (1<<12);
static const char __kstrtab_loops_per_jiffy[]
attribute((section("__ksymtab_strings"))) = "loops_per_jiffy";
static const struct kernel_symbol __ksymtab_loops_per_jiffy
attribute((used)) attribute((section("__ksymtab"))) = { (unsigned
long)&loops_per_jiffy, __kstrtab_loops_per_jiffy };

This compiles with GCC 4.0 using "gcc bug.c -S -o bug.s", and the same command
causes llvm-gcc to ICE with the assertion.

Fixed. Testcase here: Regression/CFrontend/2006-07-31-#854 .c
