The solib-search-path isn't sufficient, I think GDB opens /lib/libpthread.so.0 on my system. http://www-look-4.com/ It would be more appropriate to use "set sysroot" in this situation. When setting the sysroot, to the base of what you provided, then the correct /lib/libpthread.so.0 is loaded by GDB. http://www.compilatori.com/ Another note for those trying to reproduce: if you have a --enable-targets=all GDB, it will (erroneously) http://www.wearelondonmade.com/ detect the core as having the Symbian osabi and then tell you that it doesn't know how to handle cores. Use "set osabi GNU/Linux" to force it to use that osabi. http://www.jopspeech.com/ So now the status is that I do get a crash, but I think it's not the same as you, I think it's earlier. http://joerg.li/ I build with --enable-ubsan, and that looks like an undefined behabior sanitizer message $ ../gdb -nx --data-directory=../data-directory http://connstr.net/ (gdb) set osabi GNU/Linux (gdb) set sysroot /home/simark/build/binutils-gdb/gdb/repo (gdb) file Foo Reading symbols from Foo... http://embermanchester.uk/ (gdb) core-file Foo-core warning: Can't open file http://www.slipstone.co.uk/ /media/mmcblk0p1/install/usr/bin/Foo during file-backed mapping note processing warning: Can't open file /lib/libm-2.21.so during file-backed mapping note processing warning: Can't open file /lib/libpthread-2.21.so during file-backed mapping note processing http://www.logoarts.co.uk/ warning: Can't open file /lib/libgcc_s.so.1 during file-backed mapping note processing warning: Can't open file /media/mmcblk0p1/install/usr/lib/libstdc++.so.6 during file-backed mapping note processing warning: Can't open file /lib/libc-2.21.so http://www.acpirateradio.co.uk/ during file-backed mapping note processing warning: Can't open file /lib/ld-2.21.so during file-backed mapping note processing [New LWP 29367] [New LWP 29368] https://waytowhatsnext.com/ warning: Could not load shared library symbols for 5 libraries, e.g. /lib/libc.so.6.
