Note that in C++ the static keyword is implicit for const objects. In C however it is not, and we get clashes at link time after including the header from more than one C file: lib.a(bar.o):(.rodata+0x0): multiple definition of `__tsan_mutex_linker_init' lib.a(foo.o):(.rodata+0x0): first defined here lib.a(bar.o):(.rodata+0xc): multiple definition of `__tsan_mutex_not_static' lib.a(foo.o):(.rodata+0xc): first defined here <snip> Indeed both foo.o and bar.o define the clashing symbols: $ nm foo.o <snip> 0000000000000000 R __tsan_mutex_linker_init 000000000000000c R __tsan_mutex_not_static <snip> Fix it by explicitly making the constants static.
