This simple code #include <math.h> int main () { float A[2]; float pH = 0.1; sincosf(pH, &A[0], &A[1]); return 0; } cause segmentation fault on several linux distro & glibc versions, at lest: SuSE Linux, gcc-3.3.3 & glibc-2.3.3, with -fno-builtind; Gentoo Linux, gcc-3.4.4 & glibc-2.3.4, with -O3 -fno-builtind options; The bug resides on the glibc library since there is no segfault without -fno-builtind option on some distro.
Kindly read the manpage and/or turn up your warning level. That it happens to work with gcc's own sincosf() is pure luck, you're missing #define _GNU_SOURCE.
