could able to understand about this issue. Here is the link that i have verified https://bugzilla.redhat.com/show_bug.cgi?id=959013

shows that the size of vdso file is not enough. which is in path /proc/self/maps.

please let me know what kind of issue is this and please suggest a fix for this.

Answer 1

what kind of issue is this

Any crash inside malloc or free is a sure sign of previous heap corruption.

Use Valgrind or AddressSanitizer (incorporated into GCC-4.8 as well) to find the root cause.

Ignore vdso -- as Tom Tromey said, it has nothing to do with the problem.
