When an xterm which is built with GCC 4.1 is started, the following output (or similar garbage characters) is written to stderr: xterm: Cannot allocate color ;GuD$GTº Gterm: Cannot allocate color j éU and the terminal fails to display colour.

CFLAGS="-march=athlon-xp -O0 -pipe -fomit-frame-pointer" ^^^^ -O0 is one of the best way to get a broken system...
I do mistake in -O0 xterm wa build before with -Os !!! with -O0 or with -O1, -O2 work well
(In reply to comment #2) > CFLAGS="-march=athlon-xp -O0 -pipe -fomit-frame-pointer" > ^^^^ > > -O0 is one of the best way to get a broken system... > Why? I expect till today that this is safe, because gcc does not optimize.
I have just tried rebuilding xterm with -O0, -O1, -O2, -O3, -Os and it only shows this behaviour with -Os (although -Os works on GCC 3.4.6).
*** Bug 127346 has been marked as a duplicate of this bug. ***
Created attachment 91616 [details] shortened example The attached program displays the same bug (occurring in xterm's VTInitialize function): compiling with -O[0123] displays "0\n" x 256, but compiling with -Os displays a seemingly random -108 as well.
x 256 is too many, sorry, but that's not the point. Is this something to report to the GCC folks?
confirmed on x86 ... i'll try e-mailing the gcc lists
Seems that with versions beyond 215 it also causes xterm to seg fault, I managed to fix it by merely doing replace-flags -Os -O2 in the ebuild here.
*** Bug 146442 has been marked as a duplicate of this bug. ***
Fixed this issue with a simple replace-flags command in the ebuild and made it an overlay. This could easily be made standard and pushed out but I guess if it could be fixed upstream that would be better.
It will be fixed in 4.1.2, according to the GCC bugtracker, so is it worth it?
this will be in gcc-4.1.1-r2+
