Hi all,
I am experiencing a strange issue with gfortran. Compiling a simple program:
$ cat end.f90
end
$ gfortran end.f90 -o end
f951: Fatal Error: Cannot open pre-included file '\xe0\xd4\xf2,'
compilation terminated.
Yes, the program is doing nothing, but can not be compiled. The pre-included
file name changes randomly. Looks like something is either overwritten or
not initialized properly. I bisected this issue down to
commit f23bac62f46fc296a4d0526ef54824d406c3756c
Author: John Ericson <g...@johnericson.me>
Date: Fri Aug 22 22:24:56 2025 -0400
driver: Rework for_each_path using C++
but I do not see, why this should affect gfortran's ability to build a simple
program. I have checked the commit pre to f23bac and with that gfortran
compiles the end.f90 fine.
Running gfortran with valgrind --trace-children=yes gives the attached log.
!!! Note !!! This happens only on a stage1-only gfortran build on
x86_64-pc-linux-gnu / F41.
This is the configure and make call:
LANG=C "${SRCPATH}/configure" \
--disable-multilib\
--enable-stage1-languages=c,fortran,c++\
--enable-checking=yes \
--enable-offload-defaulted \
--prefix="${INSTALLPATH}" \
CFLAGS="-g -O0 -DENABLE_ASSERT_CHECKING" CXXFLAGS="-g
-O0"\ STAGE1_CFLAGS="-g -O0 -DENABLE_ASSERT_CHECKING"
STAGE1_CXXFLAGS="-g -O0"
make configure-stage1-gcc && \
make -j 16 all-stage1
SRCPATH points to master at 9f94029829daf3b83bb95226dcfe003c5ddcade2.
Oddly though, using a bootstrapped-build of gfortran does not suffer from the
issue.
Any clues anyone? What am I doing wrong?
Regards,
Andre
