/* NOTE: vinschen/2003-04-01: Disabled. It turns out that the call to
inside_entry_file destroys a meaningful backtrace under some
conditions. E. g. the backtrace tests in the asm-source testcase
are broken for some targets. In this test the functions are all
implemented as part of one file and the testcase is not necessarily
linked with a start file (depending on the target). What happens is,
that the first frame is printed normaly and following frames are
treated as being inside the enttry file then. This way, only the
#0 frame is printed in the backtrace output. */
