I am trying to run the GSL test-suite with GSL_IEEE_MODE set. The system is GNU/Linux 2.6.4-52-smp, gcc-3.3.3, gsl-1.5.90 (cvs-HEAD). Compile-flags used are ,----[CFLAGS] | -g -mcpu=i686 -pipe -O2 -Wall -mfpmath=sse -mieee-fp `---- When I run the test-suite with GSL_IEEE_MODE being undefined all tests pass. However, when I try to set GSL_IEEE_MODE it has to include `mask-all', otherwise some tests fail. Specifically sys/test.c fails at line 332 when using the following mode: ,----[GSL_IEEE_MODE] | double-precision,round-to-nearest,mask-underflow,mask-denormalized `---- ,----[gdb output] | Program received signal SIGFPE, Arithmetic exception. | 0x4003c306 in __ieee754_exp () from /lib/tls/libm.so.6 | (gdb) bt | #0 0x4003c306 in __ieee754_exp () from /lib/tls/libm.so.6 | #1 0x4003fda0 in exp () from /lib/tls/libm.so.6 | #2 0x08049bab in main () at ../../sys/test.c:332 `---- ,----[test.c:332] | inf = exp (1.0e10); `---- Is this expected? Any hints are appreciated.
