And there are plenty of those invalid CIE pointers. Seems that relocations against ehframe in case of sort-section=name are placed incorrectly (They are 4 bytes behind of the place where there should be - in resulting a32.out binary you can see 4byte-zeros) >objdump -s -j .eh_frame 32/a32.out 32/a32.out: file format elf32-i386 Contents of section .eh_frame: 0884 1400 017a5200 0894 017c0801 1b0c0404 8801 1800 08a4 b3fe 3e00 00410e08 08b4 8502420d 05448303 3800 48ff 08c4 6100 00410e08 8502410e 08d4 0c870343 0e108604 410e1483 054e0e30 08e4 02480e14 41c30e10 41c60e0c 41c70e08 08f4 41c50e04 1000 48ff 7000 0904 0200 2400 8800 0914 3cfc 9000 000e0846 0e0c4a0f 0924 0b740478 003f1a3b 2a322422 0934 1c00 017a504c 52000145 0944 1a079b00 001b 1b0c0404 8801 0954 2800 45fe 520f 0964 0300 00410e08 8502420d 05488603 0974 83040244 c341c641 c50c0404 objdump -s -j .eh_frame 32/b32.out 32/b32.out: file format elf32-i386 Contents of section .eh_frame: 0874 1400 017a5200 017c0801 0884 1b0c0404 8801 1800 1c00 0894 a7fe 3e00 00410e08 8502420d 08a4 05448303 3800 3800 20ff 08b4 6100 00410e08 8502410e 0c870343 08c4 0e108604 410e1483 054e0e30 02480e14 08d4 41c30e10 41c60e0c 41c70e08 41c50e04 08e4 1000 7400 54ff 0200 08f4 2400 8800 50fc 0904 9000 000e0846 0e0c4a0f 0b740478 0914 003f1a3b 2a322422 1c00 0924 017a504c 5200017c 08079bc9 0934 111b 1b0c0404 8801 2800 0944 2400 31fe 5200 040f 0954 ff410e08 8502420d 05488603 83040244 0964 c341c641 c50c0404 -- You are receiving this mail because: You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
[Bug gold/16895] building mariadb-5.5.37 with gold - .../libmysql_versions.ld:155:9: invalid use of VERSION in input file
https://sourceware.org/bugzilla/show_bug.cgi?id=16895 --- Comment #7 from vuvova at gmail dot com --- Thanks. I've tried these workarounds, both using -T and splitting the linker script (moving the version part into a separate file for --version-script). Both kind of worked, no more linking errors. But the resulting library wasn't the same as with GNU ld. It did not have any symbols in the libmysqlclient_16 version node. -- You are receiving this mail because: You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
[Bug ld/16807] Bad behavior with resources of Windows applications with recent binutils upgrade on Cygwin64
https://sourceware.org/bugzilla/show_bug.cgi?id=16807 --- Comment #18 from Angelo Graziosi --- (In reply to Ken Brown from comment #16) > Created attachment 7623 [details] > emacs-x64.manifest > > Sorry, I forgot to attach this. Thanks... ;-) Now I can try your test case. I can confirm the issues at step 4. ONLY if I strip test.exe.
