OK. Let's see...<br>
<br>
1. I'm using gcc 4.0<br>
2. 32 bit<br>
3. The same error occour even when there is no mps file being solved (the problem is in the 'set' submenu.<br>
4. I'm not familiar with this term, did you mean some information of
the results using a debugging tool like gdb? If so, the program goes
well, I type 'set' to enter the submenu, then 'time_limit' to set the
variable and whenever I try to enter any value greater than 999, the
following problem is detected:<br>
<br>
*** glibc detected *** free(): invalid next size (fast): 0x0804f680 ***<br>
<br>
Program received signal SIGABRT, Aborted.<br>
[Switching to Thread -1214564672 (LWP 8763)]<br>
0xffffe410 in __kernel_vsyscall ()<br>
<br>
5. Again I'm not sure if is it what you mean, but I try to run symphony
with the comand ./symphony<input>output (and I attached these two
files), and the following message still pops up:<br>
<br>
*** glibc detected *** free(): invalid next size (fast): 0x0804f680 ***<br>
Abortado<br>
<br>
(PS: Abortado means 'aborted' in portuguese)<br>
<br>
<br>
6. I'm trying to set the variable time_limit to the value of 1800. When
I start the program, I give the commands 'set', 'time_limit' and
'1800', then the error occurs. After many tests, I found that this
error don't occurs with values lower than 1000. Another strange thing
is that the manual says that the time_limit variable should be '<span style="font-weight: bold;">double</span>', but the error also occurs when I try to give it values like 3.14.<br>
<br>
<br>
I'm glad that I received this much attention, and I hope you can help me.<br>
By the way, in answer to <span id="_user_ali.baharev@gmail.com">Baharev Ali,</span>
I have to use symphony because my graduation project is about how
powerfull some of the COIN-OR tools are, and I'm making some tests with
then. But thank you for your attention!<br>
<br>
Best regards,<br>
