I have spent yet more time on this.  The following gdb transcript tells
the story: (comments after //)
The code was freshly checked out from the ArtStkMkt cvs.

Starting program: /home/bank/s9573347/src/ASM/asm
Param object 30 numBFagents  30
 intrate  0.100000
 baseline 10.000000
 eta 0.000500
 initvar 0.400021
BFParams init complete
Breakpoint 2, getInt (obj=0x14030d890, ivarName=0x1400b13c3 "numfcasts")
//the ivarName is good
    at BFParams.m:57
(gdb) step
makeProbe (obj=0x14030d890, ivarName=0x140137470 "address@hidden") //What
happened to ivarName???
    at BFParams.m:38
(gdb) info args
obj = (struct objc_object *) 0x14030d890
ivarName = 0x140137470 "address@hidden"    //Yucchhh
(gdb) set ivarName = 0x1400b13c3
(gdb) p ivarName
$13 = 0x1400b13c3 "numfcasts"             // reset ivarName
(gdb) Continuing.

Breakpoint 3, getInt (obj=0x14030d890, ivarName=0x14002b968 "\024") //Yet
another version
    at BFParams.m:58
(gdb) cont
Continuing.

Breakpoint 4, getInt (obj=0x14030d890,
    ivarName=0x14030d910 "<???\226\231'@?G?z\024???") at BFParams.m:59
(gdb) cont
Continuing.
xmalloc.c:26 xmalloc

Breakpoint 1, 0x3ff801182c4 in __tis_raise ()   //Silly ivarName -> Silly
numfcasts -> xmalloc spits the dummy
(gdb)

What is happening here?  I have checked the tests on the libraries again,
especially avcall and they all pass.
