Building with "-flto=auto" causes apps to crash

[etam]

In openSUSE all packages have by default enabled LTO (but in cases like this it can be easily disabled). Fortunately this is caught by the tests, because helpers/helper_accept_no_peer_addr crashes and a test fails.

This is probably because we're using a custom --version-script:

ip2unix/meson.build

Lines 85 to 92 in 1083369

	gen_ldscript = [python, script_gensyms, '--ldscript']
	ldscript = custom_target('ldscript', input: lib_sources, output: 'ldscript',
	command: gen_ldscript + gen_extra_args, capture: true)
	lib_ldflags += [
	'-Wl,--version-script,@0@'.format(sym_map.full_path()),
	ldscript.full_path()
	]
