I encounter a strange difference in the behaviour of NaN values between windows
32 and 64 bit. Have a look at the following program:
---
program NanExample;
uses
math;
var
a, b, c: Double;
begin
a := 0.0/0.0;
b := 0.0/0.0;
c := max(a,b);
if IsNan(c) then

Hi,
don't know where is the best place to ask about the bugtracker and mantis.
Please let me know.
I have two questions:
- Is everything is ok with steps to reproduce field in fpc bugtracker? It
never show at the issue view. Hope it saves and and at least the developers
are seeing it.
- Google

You can see it by clicking on view advanced in the top right corner
when
It should cause an exception everywhere by default (it does on PowerPC
32 bit). You have to use math.setexceptionmask if you want to mask
exceptions for invalid floating point operations:

Thanks, that fixed my problem.

Well, bash is probably the problem. FPC doesn't provide bash, so somehow
unix utilities from some other set were used (cygwin,mingw) and they
complain that they don't run in their own environment.
To test this, sanitize your PATH so that

Yes - this means that you don't have GNU tool called cmp in the PATH.

I'll see if I can find the missing cmp.exe in 64 bit version or try with the
32
bit version.
Copying the cmp.exe that comes with the Lazarus 32 bit installer to a 64 bit
installation worked.
Can this file be included in the 64 bit installer to
