[glade--] Error from calling malloc

Dear all:

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

(gdb) bt

#0 0xb7eb086b in ?? () from /lib/libc.so.6

#1 0xb7fb1000 in ?? ()

#2 0x00000010 in ?? ()

#3 0xb7f704c0 in ?? () from /lib/libc.so.6

#4 0xb7f704c0 in ?? () from /lib/libc.so.6

#5 0xbfad3e84 in ?? ()

#6 0xb7eaa7a5 in ?? () from /lib/libc.so.6

#7 0xb7eb27fe in malloc () from /lib/libc.so.6

#8 0x0804a237 in GetAvailableInTime (badTimeList=0x80db660) at random_pair.c:1171

#9 0x08049e50 in GetGlobalAvailableTxTime (thisPair=0x804d5f0) at random_pair.c:994

#10 0x080495b3 in GetStartTime (currentPair=0x804d5f0) at random_pair.c:657

#11 0x080494b3 in Schedule (sequence=0x804d170, PRINT=0) at random_pair.c:615

#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?
