At runtime, glxtest is mapped as follows:
0x000055fd9a030000 0x000055fd9a034000 0x4000 0x0 r--p glxtest
0x000055fd9a034000 0x000055fd9a038000 0x4000 0x3000 r-xp glxtest
0x000055fd9a038000 0x000055fd9a039000 0x1000 0x6000 rw-p glxtest
0x000055fd9a039000 0x000055fd9a03a000 0x1000 0x6000 rw-p glxtest
The problem here is that the last two sections can't be distinguished solely
by their mmap parameters. This would cause the wrong base address to be
inferred for the last mapping. To fix this, we can be more permissive by
allowing multiple candidates to be returned.
In practice, this only affects non-code sections, so it's not a big issue
either way.
