System: 200MHz Pentium Pro PC, Windows 2k, Cygwin.
GCC Version: 4.1.0, from cvs 2005-06-02.
Before the bug appeared: I had downloaded a fresh copy of the CVS tree, and was
attempting to build a copy of gfortran using the following commands (yes, I now
know that trying to build _in_ the source directory was a bad idea, but that
doesn't affect this bug).
setenv CFLAGS '-O2 -g'
setenv BOOT_CFLAGS '-O2'
cd gcc/gcc
../configure --enable-threads=posix --enable-sjlj-exceptions \
--disable-libmudflap --enable-languages=f95
I then ran "make bootstrap-lean", and waited. After some time (about 26
hours),
the compilation crashed, due to what we think is bug 21766 (compiler ICE on
valid code). This is not the bug that I am reporting. :)
The bug that I am reporting is what happened when I immediately re-ran "make-
bootstrap-lean" to see if this was repeatable. What happened instead was a
string of "tail: cannot open" errors, followed by make exiting with errors.
Apparently, the make process has gotten wedged into a state from which it can't
recover.
Some detailed output, to help track down what's happening. First, the output
of
make bootstrap-lean:

A check of the build directory finds that the entire "stage2" directory has
already been deleted at this point, which would explain why tail can't find the
files. FWIW, the various "stage" files that exist are "stage1_build",
"stage1_copy", "stage2_build", "stage2_copy", and "stage3_build".
Second, the tail end of the output from the first failed make (to help indicate
where in the process it crashed):

Finally, I'll note that I'll leave the build directory untouched for a few
days,
in case there are other files in it that would be useful to look at.
