Preprocessed source that allows to reproduce the bug
Hi,
I am on x86_64-unknown-linux-gnu cross-compiling to i686-pc-mingw32 with
mingwrt 3.20-2 and w32api 3.17. The complete configure flags used to compile
GCC is:
--target='i686-pc-mingw32' \
--build='x86_64-mingw32-unknown' \
--prefix='my-dir' \
--libdir='my-dir/lib' \
--enable-languages='c,c++,objc,fortran' \
--enable-version-specific-runtime-libs \
--with-gcc \
--with-gnu-ld \
--with-gnu-as \
--disable-nls \
--disable-multilib \
--without-x \
--disable-win32-registry \
--enable-threads=win32 \
--disable-libgomp \
--disable-libmudflap \
--with-cloog='my-dir' \
--with-gmp='my-dir' \
--with-isl='my-dir' \
--with-mpc='my-dir' \
--with-mpfr='my-dir' \
--with-as='my-dir/bin/i686-pc-mingw32-as' \
--with-ld='my-dir/bin/i686-pc-mingw32-ld' \
--with-nm='my-dir/bin/i686-pc-mingw32-nm'
I am trying to compile imlib2 1.4.6; however when compiling src/lib/api.c gcc
errors out:
$ i686-pc-mingw32-gcc -DHAVE_CONFIG_H -DPACKAGE_LIB_DIR=\"my-dir/lib\" [a bunch
of -I's] -save-temps -O2 -c api.c -o .libs/api.o
api.c:5411:1: internal compiler error: in symtab_nonoverwritable_alias, at
symtab.c:1234

Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <http://gcc.gnu.org/bugs.html> for instructions.
(The exact compilation command provided by the project also contains lots of
-W's and some -f's. I have confirmed that removing them still allows to
reproduce this bug.)
This issue is only reproducible with -O2 or higher. -O1 works fine.
The preprocessed source is attached.
