Re: [glade--] Error from calling malloc

[tang xinfa <tangxinfa gmail com>]

You can let your app link to debug version of libc, then you can trace into malloc. malloc is simple enough, error occurs when you specify error size of memory alloced or the system not have enough memory, this not require to trace into malloc for fix bug, try to set a break point in your code which line called malloc, and check it carefully.

Dear all:

I encountered some problem while calling malloc. Here is the back trace from gdb:

(gdb) bt

#12 0x0804886c in main () at random_pair.c:181

The first thing is: what I can do to step into functions in /lib/libc.so.6 so I can locate the problem more precisely.

Second: in what circumstances will malloc get corrupted?
