Description D.A.M. Revok 2003-03-19 01:56:33 UTC
This with CXXFLAGS==CFLAGS, and      
     
No Other Flags Whatsoever.      
      
1.4 rc3, and 
GCC 3.2.2     
     
Please fix the install-script to suppress this one setting, AND     
notify the user who foolishly used it, AND     
log it in the install-instructions-page, AND     
maybe tell the relevant GCC developers what-it-is within the bootstrap.sh     
script that mixes with this in an evil way.     
     
I'm running a Thunderbird with 512MB Crucial RAM ( tested with memtest86.com's     
version 3.0 ), and so trust my system, but since this is provably repeatable,     
and limited to this one setting ( thus far, that I know of ), it's a SW     
bug.     
     
I don't know if it happens in other architectures ( is it a logic-bug or is it    
an architecture-bug? )
Comment 1 Mark Guertin 2003-03-20 11:11:33 UTC
should we not set bootstrap to totally ignore CFLAGS? 
 
It's very obvious that giving users the ability to set this and a link to the gcc 
docs seems to make everyone an armchair expert and gives them the ability to 
break their system by adding -fidunnowhatthisdoesbutimaddingitcauseimcool 
Comment 2 Daniel Robbins (RETIRED) gentoo-dev 2003-09-09 16:19:35 UTC
We now insert reasonable defaults and our docs recommend that these defaults are used. Closing bug.
