Ok, for the fft SIGBUS things are more difficult:

First SIGBUS is in
0xf7fb3a70 in kiss_fft_f64_alloc (nfft=1024, inverse_fft=0, mem=0x45af4, 
    lenmem=0xffa6d3ac) at kiss_fft_f64.c:363
363         for (i = 0; i < nfft; ++i) {

Moving the definition of "pi" to the top of the function body fixes this.


Next problem is:
0xf7f80500 in kf_work (Fout=0x49bfc, f=0x3dac8, fstride=256, in_stride=1, 
    factors=0x45b24, st=0x45af4) at kiss_fft_f64.c:270
270           *Fout = *f;
(gdb) bt
#0  0xf7f80500 in kf_work (Fout=0x49bfc, f=0x3dac8, fstride=256, in_stride=1, 
    factors=0x45b24, st=0x45af4) at kiss_fft_f64.c:270
#1  0xf7f80580 in kf_work (Fout=0x49bfc, f=0x3dac8, fstride=64, in_stride=1, 
    factors=0x45b1c, st=0x45af4) at kiss_fft_f64.c:275
#2  0xf7f80580 in kf_work (Fout=0x49bfc, f=0x3dac8, fstride=16, in_stride=1, 
    factors=0x45b14, st=0x45af4) at kiss_fft_f64.c:275
#3  0xf7f80580 in kf_work (Fout=0x49bfc, f=0x3dac8, fstride=4, in_stride=1, 
    factors=0x45b0c, st=0x45af4) at kiss_fft_f64.c:275
#4  0xf7f80580 in kf_work (Fout=0x49bfc, f=0x3dac8, fstride=1, in_stride=1, 
    factors=0x45b04, st=0x45af4) at kiss_fft_f64.c:275
#5  0xf7f80bd0 in kiss_fft_f64_stride (st=0x45af4, fin=0x3dac8, fout=0x49bfc, 
    in_stride=1) at kiss_fft_f64.c:390
#6  0xf7f80c04 in kiss_fft_f64 (cfg=0x45af4, fin=0x3dac8, fout=0x49bfc)
    at kiss_fft_f64.c:398
#7  0xf7f82234 in kiss_fftr_f64 (st=0x45ae8, timedata=0x3dac8, 
    freqdata=0x41ad0) at kiss_fftr_f64.c:87
#8  0x00013068 in test_f64_0hz (__i__=0) at libs/fft.c:419




The problem here seems to be the following:
timedata is given as double * to kiss_fftr_f64(), casted to pointer to a struct
{ double a; double b; } and used as that in the line where it explodes.

I wonder why, the doubles in the array are all properly aligned and both
members of the struct should be aligned the same way. Any ideas? :)
