--- Comment #5 from rob1weld at aol dot com 2007-05-22 16:02 --- Thanks for confirming, Richard. It works on 4.2.0/1 and I've enclosed notes in the prior message that _probably_ explain why it is failing. In addition I just did a build (one day newer version) _without_ fold and it still halted the make and trigger a GNAT BUG in verify_flow_info. If the bootstrap is that touchy then we won't be getting many good compiles finishing (and test results submitted, and bugs fixed). Yesterday it worked, today I added --enable-stage1-checking=assert,gc,misc,rtl,rtlflag,runtime,tree and it broke. --- I'm placing this here because I am reasonably certain that it is related to the problems with the fold-const.c after examining the code.

--- Comment #1 from rob1weld at aol dot com 2007-05-21 19:09 --- I did some more testing on this issue. I started pulling off configure option a half dozen at a time. 1st I removed: --enable-initfini-array --enable-__cxa_atexit --enable-threads=posix --enable-decimal-float --with-long-double-128 --with-tls Next I removed: --enable-objc-gc --enable-concept-checks --enable-libstdcxx-debug --enable-static --enable-shared --enable-version-specific-runtime-libs --enable-gc-debug Then I removed: --enable-libssp --enable-libmudflap --enable-libgomp --enable-nls --with-included-gettext --enable-debug --enable-java-gc=boehm --with-x --x-includes=/usr/X11R6/include --x-libraries=/usr/X11R6/lib --enable-java-awt=gtk,xlib --enable-gtk-cairo --enable-qt-peer --enable-xmlj --enable-gconf-peer --enable-tool-wrappers --with-gjdoc --enable-portable-native-sync --enable-libgcj-multifile --with-stabs --enable-hash-synchronization --enable-interpreter --with-system-zlib --enable-libada It still broke each time in the _exact_ same place. Finally I removed _ALL_ options and simply used ./configure. A grep of the Makefile's BUILD_CONFIGARGS says: '--enable-languages=c,c++,fortran,java,objc' which are not enough for what I prefer - but now it builds I can add some more options back in. So now my xgcc says this: #gcc/xgcc -v Using built-in specs. Target: i686-pc-linux-gnu Configured with: /root/downloads/gcc-4_3-trunk/configure Thread model: posix gcc version 4.3.0 20070521 (experimental) The make of gcc has now passed the point where the prior ICE occurred.
