--- Comment #14 from Stan Johnson <userm57 at yahoo dot com> --- I can try to capture the offending "cc1plus" and "as" processes just before the compilation of gimple-match.cc fails in stage2; the output will look something like this (for a different cc1plus process number 19431 that is currently running): # cat /proc/19431/maps 80000000-82027000 r-xp 00000000 08:05 1823425 /var/tmp/portage/sys-devel/gcc-13.1.1_p20230520/work/build/prev-gcc/cc1plus 82028000-8202a000 r--p 02028000 08:05 1823425 /var/tmp/portage/sys-devel/gcc-13.1.1_p20230520/work/build/prev-gcc/cc1plus 8202a000-82036000 rw-p 0202a000 08:05 1823425 /var/tmp/portage/sys-devel/gcc-13.1.1_p20230520/work/build/prev-gcc/cc1plus 82036000-82070000 rwxp 00000000 00:00 0 [heap] 82070000-82601000 rwxp 00000000 00:00 0 [heap] c0000000-c0020000 r-xp 00000000 08:05 1682956 /lib/ld.so.1 c0020000-c0022000 r--p 00020000 08:05 1682956 /lib/ld.so.1 c0022000-c0023000 rw-p 00022000 08:05 1682956 /lib/ld.so.1 c0023000-c0026000 rw-p 00000000 00:00 0 c0028000-c0044000 r-xp 00000000 08:05 1515049 /usr/lib/libmpc.so.3.3.1 c0044000-c0045000 ---p 0001c000 08:05 1515049 /usr/lib/libmpc.so.3.3.1 c0045000-c0046000 r--p 0001b000 08:05 1515049 /usr/lib/libmpc.so.3.3.1 c0046000-c0047000 rw-p 0001c000 08:05 1515049 /usr/lib/libmpc.so.3.3.1 c0048000-c00b3000 r-xp 00000000 08:05 1672972 /usr/lib/libmpfr.so.6.2.0 c00b3000-c00b5000 ---p 0006b000 08:05 1672972 /usr/lib/libmpfr.so.6.2.0 c00b5000-c00b6000 r--p 0006b000 08:05 1672972 /usr/lib/libmpfr.so.6.2.0 c00b6000-c00b7000 rw-p 0006c000 08:05 1672972 /usr/lib/libmpfr.so.6.2.0 c00b8000-c0113000 r-xp 00000000 08:05 1515186 /usr/lib/libgmp.so.10.4.1 c0113000-c0115000 ---p 0005b000 08:05 1515186 /usr/lib/libgmp.so.10.4.1 c0115000-c0116000 r--p 0005b000 08:05 1515186 /usr/lib/libgmp.so.10.4.1 c0116000-c0117000 rw-p 0005c000 08:05 1515186 /usr/lib/libgmp.so.10.4.1 c0118000-c012a000 r-xp 00000000 08:05 411479 /lib/libz.so.1.2.13 c012a000-c012b000 ---p 00012000 08:05 411479 /lib/libz.so.1.2.13 c012b000-c012c000 r--p 00011000 08:05 411479 /lib/libz.so.1.2.13 c012c000-c012d000 rw-p 00012000 08:05 411479 /lib/libz.so.1.2.13 c012e000-c0172000 r-xp 00000000 08:05 1682625 /lib/libm.so.6 c0172000-c0173000 ---p 00044000 08:05 1682625 /lib/libm.so.6 c0173000-c0174000 r--p 00043000 08:05 1682625 /lib/libm.so.6 c0174000-c0176000 rw-p 00044000 08:05 1682625 /lib/libm.so.6 c0176000-c02df000 r-xp 00000000 08:05 1682906 /lib/libc.so.6 c02df000-c02e0000 ---p 00169000 08:05 1682906 /lib/libc.so.6 c02e0000-c02e2000 r--p 0016a000 08:05 1682906 /lib/libc.so.6 c02e2000-c02e6000 rw-p 0016c000 08:05 1682906 /lib/libc.so.6 c02e6000-c0ad2000 rw-p 00000000 00:00 0 c0ad5000-c25dd000 rw-p 00000000 00:00 0 ef91f000-ef948000 rw-p 00000000 00:00 0 [stack] > Git checkout master Thanks, I'll try compiling that version manually and also capture the relevant /proc output.
