>Synopsis: sincosl() segmentation fault
>Category: library
>Environment:
System : OpenBSD 7.5
Details : OpenBSD 7.5 (GENERIC.MP) #82: Wed Mar 20 15:48:40 MDT 2024

Architecture: OpenBSD.amd64
Machine : amd64
>Description:
calls to sincosl with long double arguments causes a segmentation fault.
>How-To-Repeat:
openbsd75$ cat x.c
#include <math.h>
int main(void)
{
long double theta = 0.0, s, c;
sincosl(theta, &s, &c);
}
openbsd75$ clang x.c -lm -o x
openbsd75$ ./x
Segmentation fault (core dumped)
openbsd75$
openbsd75$ gdb ./x
