I've reported this bug in April and it still exists in 1.00-pre2. So I made patches for both 0.60.x and 1.00-pre2. The patch is very simple, just use strncmp instead of strcmp. Please apply if it is OK. Here's the procedure to test this problem: Create a executable with very long name, say 'test_1234567890123456' and execute it. Try using 'killall' or 'pidof' to find/kill this program. Without this patch, you can't find the program.
