And gcc 2.7 (a.out AND ELF)

I tried to run 1.3.11 (a.out compiled), the machine boots up as expected,
but the 3rd serial device (spd_vhi) doesn't set the TR line, and gcc
dies after been called:

# gdb gcc

(gdb) run
Starting program: /usr/bin/gcc
Program received signal SIGSEGV, Segmentation fault.
0x40002a09 in __fpu_control ()
(gdb) quit

I believe it's not the typical memory/cache problem while compiling a big
file, it's much earlier!

About the hardware (cat /proc/pci w/ 1.3.11 kernel and Bridge Opt. turned ON):

tty02 and 03 are being set to the right IRQ/speed in rc.serial

Any ideas?
