[Discuss-gnuradio] Stable on Linux, many crashes on Windows and OS X

[Stefan Oltmanns]

Hello,

I want my program to be platform independent (it should work on Linux,
OS X and Windows).
Although it runs stable on Linux (Xubuntu 14.04 amd64), on both Windows
(Win 7 x64) and OS X (10.9) it´s crashing after about a minute.
For OS X I followed the build guide provided (installed using ports,
then uninstalled and compiled from source).

This is the console output:

Sometimes "VOLK: tried to free a non-VOLK pointer" does not result in a
crash and the program keeps running normally.

For Windows I compiled GNU Radio using Visual Studio 2012 (x64 build).
It´s the same here: It works fine for about a minute, then it crashes.
When I start to debug using Visual Studio, it shows me that the crash
occurred in the free-function (I cannot see the call stack).


Interestingly on Linux it uses the Volk-machine "avx_64_mmx", on Mac OS
X "avx_64_mmx_orc" (on Windows I don´t know), although it´s the same
computer. Is there a difference between these two and could
"avx_64_mmx_orc" be the reason for the crashes? Can I force GNU Radio to
use another Volk-machine? Any other ideas?

Best regards
Stefan
