Make Check Failures under FC9 on Intel

Hello,

I am attempting to install and compile the svn version 8598 version of
gnuradio on a Fedora 9 Pentium 4. It compiles fine but throws errors
during make check.

!!!FAILURES!!!

Test Results:

Run: 90 Failures: 1 Errors: 0

  1. test: qa_gr_fxpt_nco::t1 (F) line: 101 qa_gr_fxpt_nco.cc

double equality assertion failed

  • Expected: -0.857728600502014

  • Actual : 0

  • Delta : 9.99999974737875e-06

It seems there is an issue both in how it computes the actual and the
Delta.

A few quick Google searches and scanning the mailing list did not show
any one else having the issue.

Is anyone else having this issue?

I believe I saw this or something like it when I tested with gcc 4.3.0
a few months ago. I didn’t worry too much about it since the list of
known bugs for the compiler was pretty long, and this was the first
release of 4.3.0 What version of g++ is shipping with F9?

$ g++ --version

I supect a compiler bug.
Here’s the list of bugs fixed from 4.3.0 to 4.3.1
http://gcc.gnu.org/bugzilla/buglist.cgi?bug_status=RESOLVED&resolution=FIXED&target_milestone=4.3.1

I suggest testing with gcc 4.3.1 and see if the problem is still
there. If it’s gone, problem solved, otherwise there’s more sleuthing
to do.

I ran into this today with gcc 4.3.1 on Debian (testing). Line 101 of
qa_gr_fxpt_nco.cc

new_nco.sincos ((gr_complex*)new_block, SIN_COS_BLOCK_SIZE);

only fills the first 1696 members of new_block (though
SIN_COS_BLOCK_SIZE =
100000). Adding printf statements to new_nco.sincos or compiling
qa_gr_fxpt_nco.cc with -O1 makes the problem go away.

Thanks for creating the small test case and filing the bug against gcc!
