--- Comment #10 from H.J. Lu <hjl.tools at gmail dot com> --- (In reply to Andrew Stubbs from comment #9) > No, it's the call to bfd_set_section_contents in which the UB occurs.

We need a testcase for interleave. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
