Re: Crash when launched -nw on Mac OS X, compiled with gcc 4.0.1

[Richard Stallman]

    When hitting the breakpoint d is 7.1699012343114344e-308 (__DBL_MIN__  

At the breakpoint, d has not yet been initialized, so this value
is just garbage and tells us nothing.

What is the value of d before line 561?  That could mean something.
What value does extract_float return?
 
However, ultimately you will need the help of someone who thoroughly
knows this machine and its OS to figure out why that line is crashing,
whether it was compiled correctly, etc.
