--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> --- Created attachment 59060 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=59060&action=edit reduced testcase That's what reduction ended up with. Clean with -Wall, it no longer requires -p to trigger (but still -g). > ./cc1 -fpreprocessed ipmr.i -quiet -mno-fdpic -mabi=aapcs-linux -mfpu=vfp > -marm -mtune=arm1136j-s -mfloat-abi=soft -mlibarch=armv6k -march=armv6k -g > -O2 -std=gnu11 -version -fno-strict-aliasing ipmr2.i:185:1: internal compiler error: Segmentation fault 185 | } | ^ 0xa1ecff crash_signal /home/rguenther/src/gcc-14-branch/gcc/toplev.cc:319 0x5c7b54 canonical_cselib_val(cselib_val*) /home/rguenther/src/gcc-14-branch/gcc/cselib.h:121 0x5c7b54 rtx_equal_for_cselib_1(rtx_def*, rtx_def*, machine_mode, int) /home/rguenther/src/gcc-14-branch/gcc/cselib.cc:963 0x5c7fa9 rtx_equal_for_cselib_1(rtx_def*, rtx_def*, machine_mode, int) /home/rguenther/src/gcc-14-branch/gcc/cselib.cc:1146 0x5c7d9e rtx_equal_for_cselib_1(rtx_def*, rtx_def*, machine_mode, int) /home/rguenther/src/gcc-14-branch/gcc/cselib.cc:1021 0x5cb628 cselib_hasher::equal(cselib_val const*, cselib_hasher::key const*) /home/rguenther/src/gcc-14-branch/gcc/cselib.cc:167 0x5cb628 hash_table<cselib_hasher, false, xcallocator>::find_slot_with_hash(cselib_hasher::key* const&, unsigned int, insert_option) /home/rguenther/src/gcc-14-branch/gcc/hash-table.h:1077 0x5c5712 cselib_find_slot /home/rguenther/src/gcc-14-branch/gcc/cselib.cc:627 0x5c6479 cselib_lookup_1 /home/rguenther/src/gcc-14-branch/gcc/cselib.cc:2382 0x5c6479 cselib_lookup(rtx_def*, machine_mode, int, machine_mode) /home/rguenther/src/gcc-14-branch/gcc/cselib.cc:2446 0x5c9c60 cselib_record_sets /home/rguenther/src/gcc-14-branch/gcc/cselib.cc:2947 0x5cad75 cselib_process_insn(rtx_insn*) /home/rguenther/src/gcc-14-branch/gcc/cselib.cc:3174 0xd22573 vt_initialize /home/rguenther/src/gcc-14-branch/gcc/var-tracking.cc:10290 0xd2804a variable_tracking_main_1 /home/rguenther/src/gcc-14-branch/gcc/var-tracking.cc:10518 0xd2804a variable_tracking_main() /home/rguenther/src/gcc-14-branch/gcc/var-tracking.cc:10571 0xd2804a execute /home/rguenther/src/gcc-14-branch/gcc/var-tracking.cc:10608 Please submit a full bug report, with preprocessed source (by using -freport-bug).
