precision when calling a C function; presence of Fortran call
...fects the result of a floating-point operation. I have C functions void test1(int *n, double *f){ int outC; double c0; c0 = (double) *n * *f; outC = floor(c0); printf("when f computed by R, C says %d by itself\n",outC); } void test2(int *n, double *f){ extern int F77_NAME(ifloor)(double *); int outC,outFor; double c0; c0 = (double) *n * *f; outFor = F77_CALL(ifloor)(&c0); outC = floor(c0); printf("when f computed by R, C says %d, Fortran says %d\n",outC,outFor); } where the Fortran function ifloor is integer function ifloor(x) DOUB...

I'd be very tempted to say that that line couldn't possibly cause a bus fault (at least on x86)... but you seem to have evidence to...

Ices Crashing (BUS error)
Hi, I'm currently migrating from Shoutcast/MP3 to Icecast/OGG/Vorbis using ices. Unfortunately, when initialising the encoder, ices crashes with a bus error. Is there anything I can look into? Details as follows: icecast2-2.1.0,1 ices-2.0.0,1 libshout2-2.0_5,1 libogg-1.1.2_1,3 libvorbis-1.1.0_1,3 (All were installed from the ports tree) On FreeBSD ares.radiozilvervos.com 5.3-RELEASE-p4

loess returns different standard errors for identical models (PR#7956)
Full_Name: Benjamin Tyner Version: 2.1.0, 4/18/2005 OS: i686-redhat-linux-gnu Submission from: (NULL) (4.64.8.220) # Just run my.test() below in a newly opened R session. Once too many models have been fit (~20 on my system), the computed standard error jumps to a different value. This is (superficially) due to a different residual sum of squares, not a different one.delta. No other aspect of
