All that I know is that it's the linux kernel 4.14.57. I could provide my
config but I don't know how to proceed. It also happens with 4.14.58. The
relevant portion of my config is
CONFIG_HAVE_GCC_PLUGINS=y
CONFIG_GCC_PLUGINS=y
# CONFIG_GCC_PLUGIN_CYC_COMPLEXITY is not set
# CONFIG_GCC_PLUGIN_LATENT_ENTROPY is not set
CONFIG_GCC_PLUGIN_STRUCTLEAK=y
CONFIG_GCC_PLUGIN_STRUCTLEAK_BYREF_ALL=y
# CONFIG_GCC_PLUGIN_STRUCTLEAK_VERBOSE is not set
CONFIG_GCC_PLUGIN_RANDSTRUCT=y
CONFIG_GCC_PLUGIN_RANDSTRUCT_PERFORMANCE=y
because it stops in the tests to see if gcc plugins are supported.
It could be an error in the kernel. I tried 4.17.10 and compilation worked.
