When I attempt to compile a java source file with gcj and use the -fprofile-arcs flag I get a segmentation fault. Reproducible: Always Steps to Reproduce: 1. gcj --main Fibonacci Fibonacci.java -fprofile-arcs Actual Results: storri@base ~/Documents/StephenTorri/comp6210 $ gcj --main=Fibonacci Fibonacci.java -fprofile-arcs Fibonacci.java:1: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://bugs.gentoo.org/> for instructions. Expected Results: Program to compile. class Fibonacci { public int calculate ( int n ) { int output = 0; if ( n > 1 ) { output = calculate ( n - 1 ) + calculate ( n - 2 ); } else { output = n; } return output; } public static void main ( String[] inc ) { if ( inc.length > 0 ) { Fibonacci f_ref = new Fibonacci(); int n = Integer.parseInt(inc[0]); while ( n != -1 ) { System.out.println( "Calculated fibonacci number: " + f_ref.calculate ( n ) ); n--; } } return; } } --------------------------------- storri@base ~/Documents/StephenTorri/comp6210 $ emerge --info Portage 2.1.2-r9 (default-linux/x86/2006.1, gcc-4.1.1, glibc-2.5-r0, 2.6.18-gentoo-r6 i686) ================================================================= System uname: 2.6.18-gentoo-r6 i686 Intel(R) Pentium(R) 4 CPU 3.00GHz Gentoo Base System release 1.12.9 Timestamp of tree: Tue, 27 Feb 2007 08:50:01 +0000 distcc 2.18.3 i686-pc-linux-gnu (protocols 1 and 2) (default port 3632) [disabled] dev-java/java-config: 1.3.7, 2.0.31 dev-lang/python: 2.4.3-r4 dev-python/pycrypto: 2.0.1-r5 sys-apps/sandbox: 1.2.17 sys-devel/autoconf: 2.13, 2.61 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10 sys-devel/binutils: 2.16.1-r3 sys-devel/gcc-config: 1.3.14 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.17-r2 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=pentium4 -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/share/X11/xkb /usr/share/config" CONFIG_PROTECT_MASK="/etc/env.d /etc/env.d/java/ /etc/gconf /etc/java-config/vms/ /etc/revdep-rebuild /etc/terminfo /etc/texmf/web2c" CXXFLAGS="-O2 -march=pentium4 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig buildpkg distlocks fixpackages metadata-transfer sandbox sfperms strict" GENTOO_MIRRORS="http://lug.mtu.edu/gentoo ftp://ftp.ndlug.nd.edu/pub/gentoo/" LINGUAS="en en_GB" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --delete-after --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.namerica.gentoo.org/gentoo-portage" USE="X berkdb bitmap-fonts cli cracklib crypt cups dbus dri fortran gdbm gpm hal iconv ipv6 isdnlog kdeenablefinal kdexdeltas libg++ midi ncurses nls nptl nptlonly pam pcre perl pic ppds pppd python readline reflection session spl ssl tcpd truetype truetype-fonts type1-fonts unicode x86 xorg zlib" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1 emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mulaw multi null plug rate route share shm softvol" ELIBC="glibc" INPUT_DEVICES="keyboard mouse" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="en en_GB" USERLAND="GNU" VIDEO_CARDS="nv vga" Unset: CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, LDFLAGS, MAKEOPTS, PORTAGE_RSYNC_EXTRA_OPTS, PORTDIR_OVERLAY
This works fine with gcc-4.3
