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.
