Given a one-liner as program code, the following compilation instruction
doesn't succeed:

$ gcc32 -fprofile-arcs -o xxx xxx.c                   

/var/tmp//ccGqFanl.o(.stab+0x14): undefined reference to `LPBX0'
collect2: ld returned 1 exit status

The verbose output is attached.
The same make script works under Linux with default gcc-3.2.

Fix: None known. ktrace(1) didn't offer any hint I could understand.
How-To-Repeat: 
I think you can use any program, but I used:

main()
{
  puts("moin.");
}
