Subject: [PATCH] gdb/linespec.c: Fix missing source file during breakpoint re-set
Date: Fri,  7 Oct 2022 19:44:28 -0400	[thread overview]
Message-ID: <> (raw)

During breakpoint re-setting, the source_filename of an
explicit_location_spec is used to lookup the symtabs associated with
the breakpoint being re-set.  This source_filename is compared with each
known symtab filename in order to retrieve the breakpoint's symtabs.

However the source_filename may have been originally copied from a
symtab's fullname (the path where GDB found the source file) when the
breakpoint was first created.  If a breakpoint symtab's filename and
fullname differ, this will cause a NOT_FOUND_ERROR to be thrown during

Fix this by using a symtab's filename to set the explicit_location_spec
source_filename instead of the symtab's fullname.
