ok, using info threads i found:
128 Thread 128 (runnable) 0x08055b82 in pack (buf=0x2826b498, fmt=0xdff2 <Address 0xdff2 out of bounds>) at etip.c:618
then:
(gdb) thread 128

No symbol table info available.
i use pack function this way only in my program:
int
pack(void *buf, const char *fmt, ...);
pack(buf_0 + 8, "sc", term_code, oper_code);
i.e. second argument is format specifyer like fmt in printf.
Actually this is the function from book of Kernighan & Pike
Practice of Programming. I just checked all the code - everywhere
threre are static strings.
btw. how to get the real backtrace? It is imposiible
that this function is called from ldexp()
thank you.
