From 1d1f1ccb331f1fe9825c3bb6f6231a3aeb560d6f Mon Sep 17 00:00:00 2001 From: Markus Metzger Date: Thu, 22 May 2014 08:47:42 +0200 Subject: make_corefile_notes: have caller free returned memory The various make_corefile_notes implementations for gdbarch as well as target currently make an xfree cleanup on the data they return. This causes problems when trying to put a TRY_CATCH around the make_corefile_notes call. Specifically, we get a stale cleanup error in restore_my_cleanups. Omit the make_cleanup and have the caller free the memory. gdb/ * fbsd-nat.c (fbsd_make_corefile_notes): Remove make_cleanup call. * gcore.c (write_gcore_file): Free memory returned from make_corefile_notes. * linux-tdep.c (linux_make_corefile_notes): Remove make_cleanup call. * procfs.c (procfs_make_note_section): Remove make_cleanup call. --- gdb/gcore.c | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'gdb/gcore.c') diff --git a/gdb/gcore.c b/gdb/gcore.c index e225080..5427962 100644 --- a/gdb/gcore.c +++ b/gdb/gcore.c @@ -68,6 +68,7 @@ create_gcore_bfd (const char *filename) void write_gcore_file (bfd *obfd) { + struct cleanup *cleanup; void *note_data = NULL; int note_size = 0; asection *note_sec = NULL; @@ -81,6 +82,8 @@ write_gcore_file (bfd *obfd) else note_data = gdbarch_make_corefile_notes (target_gdbarch (), obfd, ¬e_size); + cleanup = make_cleanup (xfree, note_data); + if (note_data == NULL || note_size == 0) error (_("Target does not support core file generation.")); @@ -104,6 +107,8 @@ write_gcore_file (bfd *obfd) /* Write out the contents of the note section. */ if (!bfd_set_section_contents (obfd, note_sec, note_data, 0, note_size)) warning (_("writing note section (%s)"), bfd_errmsg (bfd_get_error ())); + + do_cleanups (cleanup); } static void -- cgit v1.1
