Hi Wolfgang
The project was started more than a year back and that time 2009.11 was the latest version, so we are still continuing with the same. On running the back trace I found that functions to be called were from - malloc env_relocate board_init_r trap_init
To be more precise the code was dying while in the following loop from the function malloc() in dlmalloc.c. It executes the loop twice before crashing.
for (victim = last(bin); victim != bin; victim = victim->bk) { victim_size = chunksize(victim); remainder_size = victim_size - nb; if (remainder_size >= (long)MINSIZE) /* too big */ {
--idx; /* adjust to rescan below after checking last remainder */ break; }
else if (remainder_size >= 0) /* exact fit */ { unlink(victim, bck, fwd); set_inuse_bit_at_offset(victim, victim_size); check_malloced_chunk(victim, nb); return chunk2mem(victim); }
}
Also when I removed a few print(debug) statements the backtrace gave the first function to be puts instead of malloc, other functions were the same as earlier.
cpu is mpc8xx.
Thanks & Regards Saugat.

Can you please explain why you stick again with code that is > 1 year old?
I am using a MPC8XX based board( as earlier), but now the code is crashing in env_relocate() function. On applying debug prints I found that the code was failing in malloc with a Bus Fault with the following dump -
It would have been easier if you had just decoded the backtrace:
Call backtrace: 00FC9988 00FDCD34 00FCCD60 00FC93B8 machine check
Which routines are these addresses from?
Best regards,
