Hi Tom,
what you are writing is completely right. Simply increasing the sampling
frequency will result in a more complex filter.
Nevertheless the firdes.low_pass function does NOT want to calculate the
101-tap-filter. But it DOES calculate the 11-tap-filter. Really

As I said, I cannot design a filter with a sampling frequency below 1e6.
The Python script I posted (where f_s = 1e3) does NOT work! But if I
change f_s to 1e6 it works and gives me the gigantic filter.

Thank you, Tom!
I will try it on my Raspi soon.

Hello again,
meanwhile I got some more information about the error.
It occurs when returning the taps from the firdes::low_pass function.
But ONLY under some conditions.

Hi everyone,
I am using the latest GNU Radio version compiled and running on a
Raspberry Pi with Raspbian Wheezy.
Most of the blocks seem to work. But the Rational Resampler makes problems.
Here is my sample python script generated by GNU Radio Companion:

Hi Frederik, hi rest,
this is an interesting error. You might want to report it.
The interesting part of your backtrace is
#8 ~vector (this=0xbee7c59c, __in_chrg=optimized out)
at /usr/include/c++/4.6/bits/stl_vector.h:350
#9 gr::filter::firdes::low_pass (gain=optimized out,
I pulled and compiled the latest gnuradio yesterday on an intel machine.
My project uses the rational resampler as well and I am having no problems.
