Bug ID: 16687
Summary: GDB Reports Incorrect Hexadecimal Value when adding
floats
Product: gdb
Version: 7.4
Status: NEW
Severity: normal
Priority: P2
Component: c++
Assignee: unassigned at sourceware dot org

Example
#include <stdio.h>
float value = 3.1415 + 299792458;
int main()
{
fprintf(stdout, "Value is %f\n", value);
return 0;
}
this program, when not compiled with -g flag reports "sum" as being ==
0x4d8ef3c2
with -g flag, it reports it as being == 0x11de7840
all you need to run is $ p/x value to see the behavior
