Package: gcc-4.6 Version: 4.6.0-10 Severity: important
It seems that gcc-4.6 tries to use some instruction unsupported by my old Pentium MMX, and gets killed by SIGILL: % gcc -E - < /dev/null gcc: internal compiler error: Illegal instruction (program cc1) Please submit a full bug report, ... % /usr/lib/gcc/i486-linux-gnu/4.6/cc1 zsh: illegal hardware instruction /usr/lib/gcc/i486-linux-gnu/4.6/cc1 An extra log message: Illegal instruction occurred at 080db3b2 in /usr/lib/gcc/i486-linux-gnu/4.6/cc1 which brings us to a faulty cmove instruction in main(): ... 80db3a7: 81 e2 00 00 00 02 and $0x2000000,%edx 80db3ad: b8 f0 b4 7c 08 mov $0x87cb4f0,%eax 80db3b2: 0f 44 f0 cmove %eax,%esi 80db3b5: eb b9 jmp 80db370 <main+0x80> 80db3b7: 90 nop 080db3b8 <_start>: 80db3b8: 31 ed xor %ebp,%ebp ... IIRC, cmov instructions aren't supported on my hardware. I confirm that gcc-4.5 works fine. -- System Information: Debian Release: wheezy/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: i386 (i586) Kernel: Linux 2.6.37.1-grsec Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages gcc-4.6 depends on: ii binutils 2.21.51.20110421-6 The GNU assembler, linker and bina ii cpp-4.6 4.6.0-10 The GNU C preprocessor ii gcc-4.6-base 4.6.0-10 The GNU Compiler Collection (base ii libc6 2.13-4 Embedded GNU C Library: Shared lib ii libcloog-ppl0 0.15.9-3 the Chunky Loop Generator (runtime ii libgcc1 1:4.6.0-10 GCC support library ii libgmp10 2:5.0.1+dfsg-7 Multiprecision arithmetic library ii libgmpxx4ldbl 2:5.0.1+dfsg-7 Multiprecision arithmetic library ii libgomp1 4.6.0-10 GCC OpenMP (GOMP) support library ii libmpc2 0.9-3 multiple precision complex floatin ii libmpfr4 3.0.1-3 multiple precision floating-point ii libppl-c4 0.11.2-3 Parma Polyhedra Library (C interfa ii libppl9 0.11.2-3 Parma Polyhedra Library (runtime l ii libquadmath0 4.6.0-10 GCC Quad-Precision Math Library ii zlib1g 1:1.2.3.4.dfsg-3 compression library - runtime Versions of packages gcc-4.6 recommends: ii libc6-dev 2.13-4 Embedded GNU C Library: Developmen Versions of packages gcc-4.6 suggests: pn binutils-gold <none> (no description available) pn gcc-4.6-doc <none> (no description available) pn gcc-4.6-locales <none> (no description available) pn gcc-4.6-multilib <none> (no description available) pn libgcc1-dbg <none> (no description available) pn libgomp1-dbg <none> (no description available) pn libmudflap0-4.6-dev <none> (no description available) pn libmudflap0-dbg <none> (no description available) pn libquadmath0-dbg <none> (no description available) -- no debconf information -- To UNSUBSCRIBE, email to debian-gcc-requ...@lists.debian.org with a subject of "unsubscribe".
