Flex crash while building AOSP

I encountered a Flex crash while building AOSP. The crash as follows:


[  1% 618/35534] Lex: aidl <= system/tools/aidl/aidl_language_l.ll
FAILED: /bin/bash -c "prebuilts/misc/linux-x86/flex/flex-2.5.39 -oout/host/linux-x86/obj/STATIC_LIBRARIES/libaidl-common_intermediates/aidl_language_l.cpp system/tools/aidl/aidl_language_l.ll"
flex-2.5.39: loadlocale.c:130: _nl_intern_locale_data: Assertion `cnt < (sizeof (_nl_value_type_LC_TIME) / sizeof (_nl_value_type_LC_TIME[0]))' failed.
Aborted (core dumped)



Turns out this is because LC_ALL is set to nothing in my machine in Ubuntu 18.04. You can see this variable by typing "locale" in the command line. To fix this just do a:

export LC_ALL=C
