The MATLAB 7.0 beta for AMD64 crashes when I create a surface object. For example, when I run the Klein Bottle demo (XPKLEIN), I get the following error:

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:
This has been verified as a bug in MATLAB 7.0 (R14) related to the system's locale, as specified by the LANG environment variable.
Currently, to work around this issue, unset LANG by running the following command before launching MATLAB:
 unsetenv LANG
