Description Karl 2011-02-25 17:58:59 EST
abrt version: 1.1.14
architecture: x86_64
Attached file: backtrace
cmdline: gnumeric /home/karlh/Desktop/gnumeric-bugtest.gnumeric
comment: The crash occurs because the constraint isn't preserved on the save and reload; instead of $A$1 >= 0 it says $A$1 >= #REF#.  The solver doesn't check for the improper constraint on file open either.
component: gnumeric
crash_function: gnm_solver_constraint_get_part
executable: /usr/bin/gnumeric-1.10.13
package: gnumeric-1:1.10.13-1.fc13
rating: 4
reason: Process /usr/bin/gnumeric-1.10.13 was killed by signal 11 (SIGSEGV)
release: Fedora release 13 (Goddard)
time: 1298674152
uid: 500

How to reproduce
Easily reproduced:
1. Open new file and enter random numbers in A1:A5
2. Set cell B1 to "=(A1-5)^2" and fill down to B5
3. Set cell B7 to "=SUM(B1:B5)"
4. Open Solver; tell it to set $B$7 -> Min by changing $A$1.
5. Add a constraint:  $A$1 >= 0; click "Add"
6. Save the file and close it.
7. Open the file you just saved.
8. Open Solver and click "Solve".

It happens here. CCing upstream.
Comment 3 M Welinder 2011-02-26 08:28:07 EST
Crash fixed here:


Saving is fine, but loading mangles the right-hand side.  I'll have a look
at that too.
Comment 4 M Welinder 2011-02-26 08:58:29 EST
Reading and a further problem fixed here.


However, results are still bogus, but that's your own fault: the model
is not linear.  Use the non-linear solver instead.
Comment 5 Julian Sikorski 2011-02-26 13:49:53 EST
Should I patch the Fedora package with these, or would it be enough if the fix shipped with the next gnumeric version?
Comment 6 M Welinder 2011-02-26 17:48:38 EST
They'll ship with the next version in, I guess, a few weeks.
That ought to be good enough.  The reporter can build with patches if he
really needs it before then.
Comment 7 Karl 2011-02-27 20:11:04 EST
Thank you for your prompt fixes---I look forward to the next version.
