signal 11

Dear "Fedorian" members ... I was installing a software of chemistry and I come to an error when trying to launch the program is Unio ..;does not matter what it does.
What it matters is when I follow the same instructions in another machine with Ubuntun 11.11 it works fine.

but in Fedora I get this simple error message:

/Desktop/UNIO_10/Unio-Linux exiting on signal 11

exiting on signal 11 ...any idea of what might be??

Thanks ... the guy that developed the program have no idea what it is!!
If you need more information please just ask.

Machine:

Fedora 15-64; I7, 3.2 GHz; HD6700 2Gb.

Signal 11 is usually where the program addresses a memory location that isn't assigned to it.

There are numerous things that can cause it, like dereferencing an uninitialized pointer, dereferencing freed memory, writing past the end of an array, stack overflows, or some recursive function that uses all of the stack space.

Sometimes segfaults can be hard to find, but just about all can be found by running the application in a debugger and when it gets the segfault, then run a backtrace on it to find out where it happened. You can run the program in gdb when it segfaults, it will tell you where and then you can step into the code to get more information.

If the guy that developed the program has no idea what a segfault is, and has no idea how to find it, then it's a poorly written program to start with. Just about every developer of applications more than a couple of lines has run into a segfault before, and pretty much knows how to find them. So either he wasn't much of a developer to start with, or he was just telling you that because he didn't want to take the time to work with you to find the problem.

Thanks,
I'll talk with him ...he is a chemist which makes the program available for free... so I cannot complain much.
But the fact that works fine on Ubuntu and not on Fedora it inverts my eye-balls.
