Well, we are squatting on ia64-pc-linux-gnu-gcc to build HelenOS, so this is
reproducible on Linux (no HelenOS-specific support exists). The testcase is our
'image.boot' loader program, but it's kind of huge. Even the function which
contains this issue, i.e. printf_core(), is pretty huge and inlines lots of
other functions.
