Perhaps since I have a 32bit userspace (I verbatim copied Host/Build from the
configure output, but although I have a 64bit kernel it's a 32bit userspace)?
After compiling with "-O0 -g" it becomes clear the problem is in the following
code:
/* Long calls stubs. */
if (htab->stub_bfd && htab->stub_bfd->sections) {
gdb says:
(gdb) print htab->stub_bfd
$1 = (bfd *) 0xf5
(gdb) print htab->stub_bfd->sections
Cannot access memory at address 0x159
(gdb)
