gcc internal error

[Jerome Lovy <Jerome.LOVY%teaser.fr@localhost>]

Hello !

I'm using gcc with vanilla NetBSD-1.2 (including kernel). These
are my first steps with NetBSD, since I only decided recently to
(temporarily) give up trying to use CyberSCSI and rather bought
some new IDE HD...

Actually, I'm trying to compile bash-2.0... During the "make"
process, I get gcc internal errors at unpredictable stage : I
mean sometimes gcc is able to compile, sometimes it produces
internal error like the following :
    gcc: Internal compiler error: program cpp got fatal signal 11
(where `cpp' is sometimes replaced with `cc1' or `as' and signal 11
with signal 4...)

Today, I even got a vm_fault straight after gcc internal error :
vm_fault(0x15e000, 10208000, 1, 0) -> 1
  type 8, code [mmu,,ssw]: 1050200
trap type 8, code = 1050200, v = 10208064
pid = 189, pc = 000EC84A, ps = 2408, sfc = 0001, dfc = 0001
...

My configuration is the following (dmesg) :
NetBSD 1.2 (GENERIC) #0: Thu Sep 26 10:27:49 EDT 1996
   
chopps%water.emich.edu@localhost:/exp/NetBSD/NetBSD-1-2/src/sys/arch/amiga/compile/GENERIC

Any clue ?
TIA,
