[Bug c++/28218] New: [4.1 Regression] ICE when building Inkscape with gcc-4.1 with -O2 -ffast-math

[vapier at gentoo dot org]

attempting to build Inkscape-1.44 with -O2 -ffast-math triggers an ICE with
gcc-4.1.1:

text-editing.cpp: In function 'void sp_te_adjust_linespacing_screen(SPItem*,
const Inkscape::Text::Layout::iterator&, const
Inkscape::Text::Layout::iterator&, SPDesktop*, gdouble)':
text-editing.cpp:1005: internal compiler error: in nearest_common_dominator, at
dominance.c:790

verified on Gentoo and Debian that 4.0.3 works, 4.1.1 fails, mainline works
