gdb: 8.1.1 -> 8.2 (#50444)
2018-11-15 23:31:05 -08:00
Initialize debug-file-directory from NIX_DEBUG_INFO_DIRS, a colon-separated list
of directories with separate debugging information files.
gdb: Look for .build-id files in NIX_DEBUG_INFO_DIRS This allows us to provide a setup hook that makes debug outputs findable by gdb.

gdb: Fix abort w/NIX_DEBUG_INFO_DIRS patch (#80929) The current gdb patch to support NIX_DEBUG_INFO_DIRS fails if the user attempts to change the debug file directory to a value other than the default. For instance: (gdb) set debug-file-directory /run/booted-system/sw/lib/debug results in: munmap_chunk(): invalid pointer Aborted (core dumped) To fix this issue, the debug_file_directory is allocated with xstrdup so that a subsequent call to xfree will succeed.
