Can you post what exactly the error message before

Hi,

You may try to increase kernel value of maxdsize.

Thanks

According to your truss output, the process received a SIGABRT which is usually due to someone pressing CTRL-C when the process is running.

I am not pressing ctrl+ c

My program is Aborting due to some reason which i am not able to figure out

$ ./test.out
Inside main()

Your truss output show the following error

mmap(NULL, 962560, PROT_READ|PROT_EXEC, MAP_SHARED|MAP_SHLIB, 6, 0x45000) .............................. ERR#12 ENOMEM

This shows that a mmap call failed due to ENOMEM, which is because there is insufficient room in the address space to effect the mapping. (as you are not useing MAP_FIXED).

So you need to increase the memory in your address space.
