'memory corruption' error when using Awk
Hello, everyone.
I got the following error when I am using awk to analysis some text file:
*** glibc detected *** awk: malloc(): memory corruption: 0x080c67f8 ***

I already search in google but can not find any clue. I've used same awk script file for various text file. some works fine, but some shows the above error.
Anyone know it? Thanks in advance.

I think this error is due to access to array that I used in awk.
