OK, export CFLAGS=-g before building seemed to be sufficient.
I'm now playing with GDB and the strange thing is, it does not catch any
fault.
The last lines executed are:
Breakpoint 1, main (argc=20, argv=0x3e4008) at

Continuing.

collect2: ld returned 5 exit status
Program exited with code 05.
(gdb)
the last "next" command makes ld exit(5).
I'll step insn by insn to find the opcode that makes it crash, so that I can
get a stack history.
