I just noticed that we run into a new regression which seems to have been introduced with gcc-5. The compiler output is as follows: gcc -DHAVE_CONFIG_H -I. -I../../../texk/web2c -I./w2c -I/«PKGBUILDDIR»/Work/texk -I/«PKGBUILDDIR»/texk -Wimplicit -Wreturn-type -g -O2 -c -o tftopl.o tftopl.c tftopl.c: In function 'mainbody': tftopl.c:1808:1: error: unrecognizable insn: } ^ (insn 9938 541 9939 36 (set (reg:SI 147 t) (eq:SI (and:SI (reg:HI 1069 [ *_271 ]) (const_int 128 [0x80])) (const_int 0 [0]))) tftopl.c:1542 -1 (nil)) tftopl.c:1808:1: internal compiler error: in extract_insn, at recog.c:2343 0x83edf3 _fatal_insn(char const*, rtx_def const*, char const*, int, char const*) ../../src/gcc/rtl-error.c:110 0x83ee2d _fatal_insn_not_found(rtx_def const*, char const*, int, char const*) ../../src/gcc/rtl-error.c:118 0x8139dd extract_insn(rtx_insn*) ../../src/gcc/recog.c:2343 0xba62f3 decompose_multiword_subregs ../../src/gcc/lower-subreg.c:1502 0xba731f execute ../../src/gcc/lower-subreg.c:1772 Please submit a full bug report, with preprocessed source if appropriate. Please include the complete backtrace with any bug report. See <file:///usr/share/doc/gcc-5/README.Bugs> for instructions. Preprocessed source stored into /tmp/ccRGajx7.out file, please attach this to your bugreport. A full build log can be found in [1]. The build log of a previous, successful build with gcc-4.9 can be found in [2]. I am attaching the preprocessed source which is mentioned in the build log.
