Breaks crtfastmath.o from gcc if debugedit is run on it, causing problems for all programs using the -ffast-math gcc switch: gcc -ffast-math test.c -o test /usr/lib/gcc/i686-pc-linux-gnu/4.3.4/crtfastmath.o:(.ctors+0x0): undefined reference to `no symbol' collect2: ld gab 1 als Ende-Status zurück Previously, an assertion would be thrown and debugedit would not be run on the file. A testscript is attached to the gentoo bug report to reproduce the error.
