[A top post noting that user "ast" CSW's are involved and other details =
in the sequence leading up to the failure.]
Using "ktrace -i -t +fw" it looks like every repeat of the problem ends =
up with the following sort of sequence (a variation is shown later):
34629 cc1 CALL =

I'll note that for the source this was compiling I used gdb truss with =
run -feH -o truss.log and it reported:
(gdb) print t->cs.number
$5 =3D 580828064
FYI: 580828064 =3D 0x229EBBA0
where the truss segmentation fault was at line 385 of the following =
(sc=3D=3DNULL in the context):

t->cs.number);

The 229E matched the upper part of local PFLT activity around the user =
"ast" CSW's, including just before the bad call.
But the details do vary some based on the source file being compiled. =
For example here the user "ast" CSW's are just before the mmap but are =
still just after the 0x229ea000 PFLT:
34698 cc1 PRET KERN_SUCCESS
34698 cc1 PFLT 0xbfbf2000 VM_PROT_WRITE
34698 cc1 PRET KERN_SUCCESS

34698 cc1 PRET KERN_SUCCESS
34698 cc1 PFLT 0x229ea000 VM_PROT_WRITE
34698 cc1 PRET KERN_SUCCESS
34698 cc1 CSW stop user "ast"
34698 cc1 CSW resume user "ast"
34698 cc1 CALL =
mmap(0,0x4000,0x3<PROT_READ|PROT_WRITE>,0x1002<MAP_PRIVATE|MAP_ANON>,0xfff=
fffff,0,0,0)
34698 cc1 RET mmap 568225792/0x21de7000
34698 cc1 PFLT 0x21de7000 VM_PROT_WRITE
34698 cc1 PRET KERN_SUCCESS
34698 cc1 PFLT 0x21de8000 VM_PROT_WRITE
34698 cc1 PRET KERN_SUCCESS

34698 cc1 PRET KERN_SUCCESS

34698 cc1 PRET KERN_SUCCESS
34698 cc1 PFLT 0x229eb000 VM_PROT_WRITE
34698 cc1 PRET KERN_SUCCESS
34698 cc1 CALL [-25840]
34698 cc1 RET [-25840] -1 errno 78 Function not implemented
34698 cc1 PSIG SIGSYS SIG_DFL code=3DSI_KERNEL
34698 cc1 NAMI "cc1.core"

34699 as Events dropped.
34699 as RET read 0
34699 as CALL close(0)
34699 as RET close 0
-25840 in 2's complement is: 0xF...F9B10
Here doing the gdb truss instead reports:
(gdb) print t->cs.number
$1 =3D 580819728
and 580819728 =3D 0x229E9B10
and the 229E part matches several PFLT's in the area, including just =
before the bad call as well as just before the user "ast"s. Between them =
are some PFLT's that do not match.
I would guess that the 229E in t->cs.number in truss is from the PFLT =
just before the failing syscall in each case.
