Package: src:f2j Version: 0.8.1+dfsg-5 Severity: important Tags: sid forky User: [email protected] Usertags: ftbfs-gcc-15
[This bug is NOT targeted to the upcoming trixie release] Please keep this issue open in the bug tracker for the package it was filed for. If a fix in another package is required, please file a bug for the other package (or clone), and add a block in this package. Please keep the issue open until the package can be built in a follow-up test rebuild. The package fails to build in a test rebuild on at least amd64 with gcc-15/g++-15, but succeeds to build with gcc-14/g++-14. The severity of this report will be raised before the forky release. The full build log can be found at: http://qa-logs.debian.net/2025/02/16/amd64exp/f2j_0.8.1+dfsg-5_unstable_gccexp.log.gz The last lines of the build log are at the end of this report. To build with GCC 15, either set CC=gcc-15 CXX=g++-15 explicitly, or install the gcc, g++, gfortran, ... packages from experimental. apt-get -t=experimental install g++ GCC 15 now defaults to the C23/C++23 standards, exposing many FTBFS. Other Common build failures are new warnings resulting in build failures with -Werror turned on, or new/dropped symbols in Debian symbols files. For other C/C++ related build failures see the porting guide at http://gcc.gnu.org/gcc-15/porting_to.html [...] f2jparse.y: In function ‘clone_ident’: f2jparse.y:4818:70: warning: iteration 7 invokes undefined behavior [-Waggressive-loop-optimizations] 4818 | new_node->astnode.ident.startDim[i] = ast->astnode.ident.startDim[i]; | ~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~ f2jparse.y:4817:13: note: within this loop 4817 | for(i=0; i<=MAX_ARRAY_DIM; i++) { gcc -Wall -DDEBUG_MEM -g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/f2j-0.8.1+dfsg=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -I /build/reproducible-path/f2j-0.8.1+dfsg/libbytecode -c f2jlex.c gcc -Wall -DDEBUG_MEM -g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/f2j-0.8.1+dfsg=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -I /build/reproducible-path/f2j-0.8.1+dfsg/libbytecode -c f2jmain.c gcc -Wall -DDEBUG_MEM -g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/f2j-0.8.1+dfsg=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -I /build/reproducible-path/f2j-0.8.1+dfsg/libbytecode -c codegen.c gcc -Wall -DDEBUG_MEM -g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/f2j-0.8.1+dfsg=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -I /build/reproducible-path/f2j-0.8.1+dfsg/libbytecode -c vcg_emitter.c gcc -Wall -DDEBUG_MEM -g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/f2j-0.8.1+dfsg=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -I /build/reproducible-path/f2j-0.8.1+dfsg/libbytecode -c typecheck.c gcc -Wall -DDEBUG_MEM -g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/f2j-0.8.1+dfsg=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -I /build/reproducible-path/f2j-0.8.1+dfsg/libbytecode -c optimize.c gcc -Wall -DDEBUG_MEM -g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/f2j-0.8.1+dfsg=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -I /build/reproducible-path/f2j-0.8.1+dfsg/libbytecode -c globals.c optimize.c: In function ‘optimize’: optimize.c:188:5: warning: case value ‘0’ not in enumerated type ‘enum _nodetype’ [-Wswitch] 188 | case 0: | ^~~~ vcg_emitter.c: In function ‘emit_vcg’: typecheck.c: In function ‘typecheck’: vcg_emitter.c:234:5: warning: case value ‘0’ not in enumerated type ‘enum _nodetype’ [-Wswitch] 234 | case 0: | ^~~~ typecheck.c:102:5: warning: case value ‘0’ not in enumerated type ‘enum _nodetype’ [-Wswitch] 102 | case 0: | ^~~~ codegen.c: In function ‘emit’: codegen.c:112:7: warning: case value ‘0’ not in enumerated type ‘enum _nodetype’ [-Wswitch] 112 | case 0: | ^~~~ codegen.c:108:9: warning: variable ‘locals’ set but not used [-Wunused-but-set-variable] 108 | int locals; | ^~~~~~ codegen.c: At top level: codegen.c:765:1: error: conflicting types for ‘free_lists’; have ‘void(JVM_METHOD *)’ {aka ‘void(struct _method_info *)’} 765 | free_lists(JVM_METHOD *meth) | ^~~~~~~~~~ In file included from codegen.c:17: codegen.h:278:3: note: previous declaration of ‘free_lists’ with type ‘void(void)’ 278 | free_lists(); | ^~~~~~~~~~ codegen.c: In function ‘getNameFromCommonDesc’: codegen.c:1847:8: warning: comparison between pointer and zero character constant [-Wpointer-compare] 1847 | if(p == '\0') | ^~ codegen.c:1847:6: note: did you mean to dereference the pointer?
