https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D279901 --- Comment #13 from bugzilla@tunedal.net --- (In reply to Konstantin Belousov from comment #12) Here are the register values you asked for. Installing the debug symbols us= ing debuginfod (or find-dbgsym-packages) doesn't seem to have changed the backtraces. The damage is presumably done by something related to memcpy/memmove since = this commit is what causes the symptoms to manifest: https://sourceware.org/git/?p=3Dglibc.git;a=3Dcommitdiff;h=3Daa4249266e9906= c4bc833e4847f4d8feef59504f;hp=3D5a461f2949ded98d8211939f84988bc464c7b4fe Python: root@localhost:~# gdb --core=3Dpython3.core GNU gdb (Debian 13.2-1+b2) 13.2 ...
