After installing an updated version of scilab 5.5.1 (previous version 5.5.0 is not affected by this bug) it is not possible to start the program using gui. The command line version (scilab-cli) works well. Reproducible: Always Steps to Reproduce: 1. compile and install scilab-5.5.1 from science overlay 2. start scilab from the command line to see crash report Actual Results: The program will crash with an SIGSEGV error. See included files to see the program backtrack and outputs. Expected Results: The program will not crash. Analysing the bug I have found out that the console input string (char*) is null in scilab/modules/console/src/c/GetCommandLine.c:120 file, whereas in scilab of version 5.5.0 it is a user input. Probably the function "ConsoleRead()" does not work correctly. ======================== emerge --info ================================ Portage 2.2.12 (python 3.3.5-final-0,

Created attachment 389124 [details] Error messages produced by scilab. I have also tried alternative JVMs with the same result. Tested JVMs: 1) dev-java/oracle-jdk-bin-1.7.0.71 2) dev-java/icedtea-7.2.5.3 3) dev-java/icedtea-bin-6.1.13.3-r3
Created attachment 389126 [details] Backtrace of the program (gdb, valgrind).
I have found out that the issue is not reproducible any more after updating the system (some libraries, compiler, etc.) and Scilab recompilation.
