On my x86_64 system, sometimes but not all the time, the following happens:
$ configure --prefix=/home/guerby/work/gcc/install/install-20041211T175809 --enable-languages=c --enable-__cxa_atexit --disable-nls --enable-threads=posix --enable-checking $ make bootstrap [...] stage1/xgcc -Bstage1/ -B/home/guerby/work/gcc/install/install-20041211T175809/x86_64-unknown-linux-gnu/bin/ -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-macros -Wold-style-definition -Werror -fno-common -DHAVE_CONFIG_H gcov.o intl.o version.o errors.o ../libcpp/libcpp.a ../libiberty/libiberty.a -o gcov stage1/xgcc -Bstage1/ -B/home/guerby/work/gcc/install/install-20041211T175809/x86_64-unknown-linux-gnu/bin/ -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-macros -Wold-style-definition -Werror -fno-common -DHAVE_CONFIG_H gcov-dump.o version.o errors.o ../libcpp/libcpp.a ../libiberty/libiberty.a -o gcov-dump [...] stage2/xgcc -Bstage2/ -B/home/guerby/work/gcc/install/install-20041211T175809/x86_64-unknown-linux-gnu/bin/ -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-macros -Wold-style-definition -Werror -fno-common -DHAVE_CONFIG_H gcov.o intl.o version.o errors.o ../libcpp/libcpp.a ../libiberty/libiberty.a -o gcov stage2/xgcc -Bstage2/ -B/home/guerby/work/gcc/install/install-20041211T175809/x86_64-unknown-linux-gnu/bin/ -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-macros -Wold-style-definition -Werror -fno-common -DHAVE_CONFIG_H gcov-dump.o version.o errors.o ../libcpp/libcpp.a ../libiberty/libiberty.a -o gcov-dump [...] make[2]: Entering directory `/home/guerby/work/gcc/build/build-20041211T175809/gcc' gcc -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -fno-common -DHAVE_CONFIG_H gcov.o intl.o version.o errors.o ../libcpp/libcpp.a ../libiberty/libiberty.a -o gcov gcc -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -fno-common -DHAVE_CONFIG_H gcov-dump.o version.o errors.o ../libcpp/libcpp.a ../libiberty/libiberty.a -o gcov-dump [...] gcov and gcov-dump are relinked with the base compiler which seems wrong. As explained in http://gcc.gnu.org/ml/gcc/2004-12/msg00106.html when ada is enabled, gnat1drv relink with the base compiler is retried which leads to a bootstrap failure. This never happened before 20041120. Is anyone seeing this? Just grep your build log with: $ cat log|grep gcov|grep libi and look at the last lines. -- Summary: x86_64 spurious relink of gcov and gcov-dump with the base compiler Product: gcc Version: 4.0.0 Status: UNCONFIRMED Keywords: build Severity: normal Priority: P2 Component: bootstrap AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: laurent at guerby dot net CC: gcc-bugs at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18939
