Package: gcc-4.3 Version: 4.3-20070902-1 Severity: normal Dear Debian GCC team,
I am preparing a package for DiAlign-T, a bioinformatic software. (http://bugs.debian.org/445983). I manage to build it with gcc-4.1, but not gcc-4.3 neither gcc-4.2. Here is the output of the compilation: chouca〔source〕$ make CC=gcc-4.3 CFLAGS='-Wall -g -O2' CPPFLAGS='' gcc-4.3 -Wall -g -O2 -c -o museq.o museq.c museq.c: In function ‘main’: museq.c:80: warning: ‘pdist’ may be used uninitialized in this function museq.c:79: warning: ‘in_seq_col’ may be used uninitialized in this function gcc-4.3 -Wall -g -O2 -c -o parameters.o parameters.c gcc-4.3 -Wall -g -O2 -c -o io.o io.c io.c: In function ‘read_fasta’: io.c:407: warning: ‘data_maxlen’ may be used uninitialized in this function io.c:406: warning: ‘slen’ may be used uninitialized in this function io.c:405: warning: ‘data’ may be used uninitialized in this function io.c:392: warning: ‘seq’ may be used uninitialized in this function gcc-4.3 -Wall -g -O2 -c -o diag.o diag.c diag.c: In function ‘find_diags_dyn’: diag.c:850: warning: ‘ap’ may be used uninitialized in this function diag.c: In function ‘find_diags_dialign’: diag.c:423: warning: ‘ap’ may be used uninitialized in this function gcc-4.3 -Wall -g -O2 -c -o alig.o alig.c alig.c: In function ‘prepare_alignment’: alig.c:637: warning: ‘max’ may be used uninitialized in this function alig.c: In function ‘adapt_diag’: alig.c:225: warning: ‘succF’ may be used uninitialized in this function alig.c:225: warning: ‘predF’ may be used uninitialized in this function alig.c: In function ‘simple_aligner’: alig.c:806: warning: ‘tclock’ may be used uninitialized in this function gcc-4.3 -Wall -g -O2 -c -o prob.o prob.c prob.c: In function ‘calc_score_dist’: prob.c:157: warning: ‘sq1’ is used uninitialized in this function prob.c:158: warning: ‘sq2’ is used uninitialized in this function prob.c:248: internal compiler error: in assign_386_stack_local, at config/i386/i386.c:15706 Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. For Debian GNU/Linux specific bug reporting instructions, see <URL:file:///usr/share/doc/gcc-4.3/README.Bugs>. make: *** [prob.o] Erreur 1 Interestingly, this bug seems to be arch-specific: I managed to build dialign-t with gcc-4.2 on a powerpc system. I do not know enough of C to say anything more... but if you want me to submit upstream and forward you the bug number I will do it.
