Re: [pygsl-discuss] Memory leak in spline module?

[Pierre S. <p.s...@gs...>]

Dear Nor,

	thanks for your bug report. I found the error and fixed it in CVS. I 
use this module frequently but not in such loops and did not yet bump 
into it. (The source of the error was a wrong swig typemap name). It is 
fixed in CVS.

A snapshot is uploaded to:
	http://pygsl.sf.net/pygsl-0.9.3.tar.gz

Please can you tell me if it fixes the problem for you?

Dear All, please could you tell me if it introduces new problems?

Sincerely yours
	Pierre
