[Bug binutils/28992] New: strip strips .gnu_debuglink
https://sourceware.org/bugzilla/show_bug.cgi?id=28992 Bug ID: 28992 Summary: strip strips .gnu_debuglink Product: binutils Version: 2.37 Status: UNCONFIRMED Severity: normal Priority: P2 Component: binutils Assignee: unassigned at sourceware dot org Reporter: cristian.adam at gmail dot com Target Milestone: --- We noticed with a MinGW 11.2.0 package that binutils 2.37's strip removes the ".gnu_debuglink" section from binaries. This was not the case with MinGW 8.1.0 and binutils 2.30. The removal of the ".gnu_debuglink" section results in gdb not loading the separate debug binaries. See how Qt is affected at https://bugreports.qt.io/browse/QTBUG-101653 The workaround is to use a script that adds "--keep-section=.gnu_debuglink". -- You are receiving this mail because: You are on the CC list for the bug.
