[ECOS] [Fwd: [ECOS] printf and floating point emulation]

[Eduardo Sabaj]

I'm working with one of the pre-built toolchains for Intel x386 which 
I've downloaded some years ago. Anyway, yesterday I downloaded this same 
toolchain from  http://ecos.sourceware.org/getstart.html.

I executed:

       wget --passive-ftp 
ftp://ecos.sourceware.org/pub/ecos/ecos-install.tcl
              sh ecos-install.tcl

Then I compiled sprintf1.c with this new environment and the result is 
the same. The program crashes with the first line with %f format.
