Post "reshape" memory leaks with icc/ia64
Odd...,
the "reshape" function, which I do not use much, has a memory leak on one of the machines I work with (ia64 altix Linux 2.6.16.54-0.2.3/ Intel compiler,) if I believe "yorick_stats()" or "top". Calling the "median" function from "std.i" repeatedly and checking memory statistics produces an increase in allocated memory. Replacing the offending "reshape" call (the first one in the function) by the equivalent "reform" solves the problem, but allocates more memory. I discovered this while using reshape to unpack some bit packed 12-bit data. I now have a compiled plugin that does this. I was looking at the "median" code to generalize an interpolator with a "which=" dimension-picking keyword, similar to that of "interp".

There is no memory leak with "reshape" on my linux/debian gcc x86_64 box.

Cheers
