Package: gcc-4.7
Architecture: i386
Version: 4.7.0-3
The compiler blows up on an Intel Pentium, because it uses cmove
internally. (I.e. is compiled for i686+)
I realize running current Debian experimental packages on a Pentium
166 is perhaps more an exercise in retrocomputing than practicality,
but I thought it was supposed to work. Certainly most other binaries do.
(Note that gcc-4.6_4.6.3-1 has the same problem which may be demonstrated
on a 0-byte null.c file.)
Running gcc normally reports illegal instruction and internal compiler
error; cc1 under the debugger makes it clearer:
(The Linux kernel source tree is v3.3.2, if it matters.)
