Subject: Epics SIGFPE?

R3.14.11 brings two new math constants epicsNAN and epicsINF. That appears to break our channel access plugin for Yorick, because the interpreter enables and is setup to catch SIGFPE.

C99 provides macros so you don't have to 'make' the value. I patched our src/libCom/osi/epicsMath.cpp. I don't guarantee this to be osi-generic and all platforms. It works for linux-x86/x86_64

diff src/libCom/osi/epicsMath.cpp src/libCom/osi/epicsMath.cpp.org

< #ifdef NAN

< #else

< #endif
< #ifdef INFINITY
< epicsShareDef float epicsINF = INFINITY;
< #else

< #endif
