Works on MinGW (MXE)3.7.7+ :

>> [fname fpath] = uigetfile ();
>> sin (3)
ans =  0.14112
>> g = 4 /8
g =  0.50000
>> clear all
>> g = 4 /3
g =  1.3333
>> cos (9)
ans = -0.91113
>> [fname fpath] = uigetfile ();
>> g
g =  1.3333

I rather think (but the OP's report isn't clear) that he hit the notorious but somewhat elusive "clear all" bug (which segfaults many MinGW-Octave 3.x.x versions).
This bug has nothing to do with uigetfile() directly, and is believed to be related to a.o., the ad and some other OF packages being loaded.
Search google for 'Octave "clear all" mingw'

If in the OP's sequence "clear all" is replaced by just "clear" it all works OK on Octave-3.6.4 for MinGW.

As it works on MinGW Octave 3.7.7+ I'll close this bug with status "fixed".

This works fine on a Linux machine with either 3.6.4 or the development version.  Someone else with a Windows machine will have to test this.

The following sequence causes the program to shut itself down:

when the uigetfile is revoked after a "clear all" command.

[fname fpath]=uigetfile() %parameters do not change the outcome
% some other commands
% other commands
clear all
% couple of other commands
[fname fpath]=uigetfile()
