Thread: help needed on debugging "bus error"

Hello. This is my first post here. Thanks for your help.

I have been coding a program which handles many arrays of strings. The program sometimes (there is a random number generator in the codes) will crash with a message "bus error".

I am guessing it's caused by those strings. I tried to find out where exactly the error occurs by adding print lines inbetween coding blocks like the following:


100 printf("100\n");

codes...

200 printf("200\n");

codes...

300 printf("300\n");

However, it didn't help because the output will be something like

100
200
300
100
20


which means it crashes in the middle of printing 200?

Anyway, because i can't exactly pin down which part of the code causes the problem, it is very hard for me to fix it.

Any ideas?

Thanks a lot.

Thanks for the reply.
Indeed it was an array index problem.

gdb helped me to find the damn line.

Thanks a lot.
