Runtime ERROR: *** glibc detected *** ./parser: malloc(): memory
corruption (fast): 0x0a26d360 ***
Hi
i am using Xerces-C - 2.7.0 with gcc-4.1.0. I successfully installed
xerces.
In my project i used this to parse my data which are in XML sheets.
Each are of size of 6.5 Mb.i am parsing xml files using DOM parsing..
when ever i parse a small file(5Kb) no problem its workin. But if with big
xml file(6.5MB) after some time of execution i am getting RUNTIME error
saying
*** glibc detected *** ./parser: malloc(): memory corruption (fast):
0x0a26d360 ***
Here wht i am getting exactly :
*** glibc detected *** ./parser: malloc(): memory corruption (fast):
0x0a26d360 ***

here i am attaching example of my data sheet. In this example sheet it
contais around 10 to 15 graph elements. My original data sheet contains
20K to 40K graph elements. If i just try to parse whole sheet i am getting
this error.
Please suggest me solution.. if u need more clear specification of my
problem please do ask me..
Thanking u in advance...

Hi,
from the stack trace it looks that your code is directly invoking
XMLString::transcode. Could you post your code for further inspection?
