Default running maq on linux ubuntu 32 bit

Thanks for the reply andpet, yes what you mentioned is true and in the above case the problem was because of that only.
I had tried running after clearing the existing output files. I would like to first mention here that i am now able to successfully execute the MAQ demo. I would also like to share another piece of experience here:
I am working on a 32 bit core 2 duo, Linux machine.
Though I was able to run the maq v0.6.8 executables, directly downloaded from the sourceforge download page, i was unable to run this version compiled from source code on my machine.
Invariably I was getting stuck at the following error during execution:

---------------------------------------------------------------------------------------------------
*** buffer overflow detected ***: /home/.../maq-0.7.1/scripts/maq terminated

.
.
.

** fail to run command '(cd maqdemo; /home/.../maq-0.7.1/scripts/maq simustat easyrun/all.map > eval.simustat)' at ./maq.pl line 842.
---------------------------------------------------------------------------------------------------

Later I discovered that it was coming because of a compile time optimization parameter in the Makefile.generic:

CFLAGS= -g -Wall -O2 -m64 # comment out `-m64' for 32-bit compilation

removed the '-O2' from the above flag and changed -m64 to -m32 (as mentioned in other posts) and compiled the source code. This solved the purpose and ran the executable to completion.
