Bug ID: 69314
Summary: Use of uninitialised value in libbacktrace/pecoff.c
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: ranma42 at gmail dot com
Target Milestone: ---
In coff_add(), str_size is declared as a size_t, but if there is a symbol
table, only 4 bytes of it are initialised:
memcpy (&str_size, syms_view.data + syms_size, 4);
str_size should probably be declared as a uint32_t.
The bug at https://github.com/rust-lang/rust/issues/28447 was caused by this.
It was fixed in Rust local copy of libbacktrace:
