testcase:
[math...@mathieu-laptop test]$ cat >test.c
__thread int g_a;
int main (int argc, char *argv[])
{
g_a = 0;
return 0;
}
[math...@mathieu-laptop test]$ gcc -fpie -pie ./test.c -o test
/usr/bin/ld: /tmp/ccsIE4YR.o: relocation R_X86_64_TPOFF32 against
`g_a' can not be used when making a shared object; recompile with
-fPIC
/tmp/ccsIE4YR.o: could not read symbols: Bad value
collect2: ld returned 1 exit status
The above works with "gcc -fpic -pie ./test.c -o test" (which, I know, is not
really supported).
