Dear Jed,

What did I do wrong on this? Nothing comes out from -malloc 0:

rebecca at YuanWork:~/linux/code/twoway/twoway_new/workingspace$ valgrind  
-malloc 0 ./twgcqt2unffnictvscj.exe -options_file option_all
valgrind: 0: command not found
rebecca at YuanWork:~/linux/code/twoway/twoway_new/workingspace$ valgrind  
--malloc 0 ./twgcqt2unffnictvscj.exe -options_file option_all
valgrind: 0: command not found

Thanks a lot!

Rebecca
