This is a build from git://sourceware.org/git/binutils-gdb.git at cbda14deaf49. (All directory names below are manually redacted and may contain typos.) I checked out gdb-binutils tree, configured with "--prefix /tmp/foo" and built and installed with "make all" and "make install".

GDB will now terminate. This is a bug, please report it. For instructions, see: <https://www.gnu.org/software/gdb/bugs/>. zsh: segmentation fault /foo/bin/bin/gdb ------- This seems to be a regression from that which Debian packaged, where "gdb --version" says "GNU gdb (Debian 10.1-1.7) 10.1.90.20210103-git", and where the corresponding "document foo" gets me the somewhat more expected: ------- (gdb) document foo Undefined command: "foo". Try "help". (gdb) ------- (FWIW, I actually sourced a script, where I had the document and define switched, but the crashing behavior is AFAICT identical.) -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 7+ messages in thread
