This seems to be hard to fix. In fact it should be added to system's libc.

stephanj,

can you please investigate the situation a bit closer?

• Is this still true with current versions?
• Is there an upstream but report?
• Any additional infos on this out on the inet?
• Any known workaround/fix?

Test code should be trivial:

 long long int a;
 printf("%lli\n", a);

Compiled with -Wall -Wextra.

$ gcc -Wall -Wextra -o llitest.exe llitest.c

Just commited a patch to rpld to fix this within rpld by replacing %llX with %lX. Commitid:2sEur26GIEGbbfkw

[ph3-der-loewe]

My patch is to avoid %llX everywhere within the normal code flow. Not updated are ROAR_DBG() debuglions. They may be converted later if needed. I still hope mingw will be fixed.
