We have verified that there is a bug in MATLAB 7.0.1 (R14SP1) when running on Fedora Core 2 machine.

To work around this issue, try the following steps:

1. Change the default charset before starting MATLAB 7.0.1 (R14SP1).

Set the environment variable from the shell using one of the following commands:

 setenv LANG en_US

or

 setenv LANG C

2. Use the old Linux threads implementation by setting the environment variable LD_ASSUME_KERNEL. Set it to either 2.2.5 or 2.4.1. If you are using the C shell, you can enter one of the following at the Linux prompt:

 setenv LD_ASSUME_KERNEL 2.4.1

or

 setenv LD_ASSUME_KERNEL 2.2.5

If you are using bash shell, you can enter one of the following at the LINUX prompt:

 export LD_ASSUME_KERNEL=2.4.1

or

 export LD_ASSUME_KERNEL=2.2.5

3. It may be possible to resolve the problem by turning off the JIT accelerator in MATLAB:

feature accel off

In the case that none of the above solutions work, some users have resolved their issue by changing the kernel to Fedora Core (2.6.9-1.6_FC2),RHFC1 or Fedora core 3.
