           Summary: [3.3.1 regression] Segmentation fault in gen-protos in
                    stage2
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: critical
          Priority: P3

/bin/sh: 26493 Memory fault(coredump)

Running gen-protos under gdb, I see:

Program received signal SIGSEGV, Segmentation fault.
0x4000000000002e64 in add_hash (fname=0x800000010000ea33 "TLappend")

Symbol "i" is a variable in register r21.

Symbol "hash_tab" is static storage at address 0x8000000100000470.
gdb) disass 0x4000000000002e5c 0x4000000000002e6c
Dump of assembler code from 0x4000000000002e5c to 0x4000000000002e6c:
0x4000000000002e5c <add_hash+172>:      extrd,s ret0,63,32,r21
0x4000000000002e60 <add_hash+176>:      depd,z r21,61,62,r22

    cmpib,= 0,r19,0x4000000000002f0c <add_hash+348>
End of assembler dump.

The C code is:

  i = hashstr (fname, strlen (fname)) % HASH_SIZE;
  i0 = i;
  if (hash_tab[i] != 0)

It looks as if this failure is caused by this patch :(

        PR Target/11453
        * pa.md: Disparage all mtsar constraints.
        (extzv, extv, insv): Don't fail on length of {32|64}.

This may also be the cause of the miscompilation reported in PR 11516.
