In MATLAB 7.0 (R14), the REGEXPREP function (and several other REGEXP functions) on some installations returns incorrect results. For example:

str = 'My flowers may bloom in May';
pat = 'm(\w*)y';
regexprep(str, pat, 'April')

The correct output is:\n

My flowers April bloom in May

However, on my computer, I observe:\n

My flowers may bloom in May

We have verified there is a bug in MATLAB 7.0 (R14) in the way that MATLAB handles an environmental variable on the system PATH called ICU_DATA.
