             Bug #: 14036
           Summary: exp(710.0) fails to set the overflow exception flag
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: math
        AssignedTo: unassigned@sourceware.org
        ReportedBy: kreckel@ginac.de
    Classification: Unclassified


Created attachment 6382
  --> http://sourceware.org/bugzilla/attachment.cgi?id=6382
test case

Using the current HEAD of glibc on an x86-64 system, 

When I run the attached program using current HEAD after compiling glibc on an
x86-64 system, I get:

exp(710) returned inf
IEEE754 exception flags: none
exp(-1234) returned 0
IEEE754 exception flags: none

The first one should have set the OVERFLOW exception flag, the second one the
UNDERFLOW exception flag.

(This appears to have broken recently.)
