[Bug tools/30772] New: dwarflint checking for specification recursion
https://sourceware.org/bugzilla/show_bug.cgi?id=30772 Bug ID: 30772 Summary: dwarflint checking for specification recursion Product: elfutils Version: unspecified Status: NEW Severity: normal Priority: P2 Component: tools Assignee: unassigned at sourceware dot org Reporter: tromey at sourceware dot org CC: elfutils-devel at sourceware dot org Target Milestone: --- This idea comes from this thread: https://sourceware.org/pipermail/gdb-patches/2023-August/201655.html The idea is that if a DIE refers to itself via a chain of DW_AT_specification (or the other ways a DIE can refer to another), then dwarflint ought to warn, as recursion like this is never valid. -- You are receiving this mail because: You are on the CC list for the bug.
[Bug libdw/26773] sleb128 values near INT64_MAX/MIN not correctly read
https://sourceware.org/bugzilla/show_bug.cgi?id=26773 --- Comment #1 from Tom Tromey --- I looked at this a little today. In addition to this bug, I think the _unchecked variants have another bug; namely they do: const size_t max = len_leb128 (int64_t) - 1; This limits the number of bytes read-- but it seems like it maybe ought to read until the first byte without the high bit set. FWIW gdb seems to rely on implementation-defined behavior here. It does all the sleb work in an unsigned type and then casts it to signed on return. -- You are receiving this mail because: You are on the CC list for the bug.
