From 79b38778d788e01e66e82f16bf3d4957439c77d5 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Fri, 29 Jun 2018 15:10:04 -0600 Subject: [PATCH] Use scoped_free_pendings in coff_symtab_read PR gdb/18624 concerns an assertion failure that occurs when setting a breakpoint in a Go program on Windows. What happens here is that coff_symtab_read uses buildsym but does not instantiate scoped_free_pendings. So, the struct pending objects are never released. Later, dwarf2read.c calls buildsym_init, which asserts. This patch fixes the problem by instantiating scoped_free_pendings in coff_symtab_read. Tested using the test executable from the PR. I don't know how to test this more fully. 2018-07-17 Tom Tromey PR gdb/18624: * coffread.c (coff_symtab_read): Use scoped_free_pendings. --- gdb/ChangeLog | 5 +++++ gdb/coffread.c | 3 +++ 2 files changed, 8 insertions(+) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 7b77e87..7388c7d 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,8 @@ +2018-07-17 Tom Tromey + + PR gdb/18624: + * coffread.c (coff_symtab_read): Use scoped_free_pendings. + 2018-07-11 Pedro Alves PR gdb/23377 diff --git a/gdb/coffread.c b/gdb/coffread.c index 30583e1..9e2edde 100644 --- a/gdb/coffread.c +++ b/gdb/coffread.c @@ -803,6 +803,9 @@ coff_symtab_read (minimal_symbol_reader &reader, CORE_ADDR tmpaddr; struct minimal_symbol *msym; + buildsym_init (); + scoped_free_pendings free_pending; + /* Work around a stdio bug in SunOS4.1.1 (this makes me nervous.... it's hard to know I've really worked around it.
