ARM: Segmentation fault when compiling tests/function-pointer.c

[florommel]

Compiling tests/function-pointer.c on ARM causes an internal compiler error (segmentation fault).
[GCC version: 6.3.1, arch: armv6l]

In directory tests:
$ gcc -o function-pointer.o -c function-pointer.c -fplugin=../gcc-plugin/multiverse.so -I../libmultiverse -Wextra -MT function-pointer.o -MMD -MP -MF .d/function-pointer.Td

found multiverse operand: config
guess!...found '1' multiverse variables (0 blacklisted)
generating function clone foo.multiverse.config_0
.. found multiverse variable in statement, replacing: config.0_1 = 0;
generating function clone foo.multiverse.config_1
.. found multiverse variable in statement, replacing: config.0_1 = 1;
Generated 2 specialized functions for foo
mv variant generation: skipping non-mv function 'main'

merge function bodies for: foo
foo.multiverse.config_0 NEQ; new equivalence class
foo.multiverse.config_1 NEQ; new equivalence class
found function equivalence class of size 1
found function equivalence class of size 1
