I just compiled linux-2.1.98 with egcs-19980425 (works fine with
egcs-980321). The result Oopses immediately, and panics(" Attempted to kill
idle task! in swapper - not syncing").  The oops is at the first line of
register_proc_table, the assembly generated by both compilers here is the
same. Somehow it is called with wrong args somewhere.

Will try to analyse further, staying at 980321 for the time being.

The current egcs in CVS doesn't even pass "make check" in libstdc++
on Linux/x86.
