[Bug debug/42396] New: ICE: in dwarf2out_frame_debug_adjust_cfa, at dwarf2out.c:1859

[zsojka at seznam dot cz]

Command line:
gcc -m32 -O2 -g -ftracer -fsched2-use-superblocks testcase.c
(x86 binary doesn't need -m32, crashes as well)

Tested versions:
trunk r155256 - crash
trunk r155121 - crash (x86)
trunk r154886 - crash (both with and without checking)
trunk r153685 - crash
4.4 r154975 - OK (with checking)

Output:
$ /mnt/svn/gcc-trunk/binary-155256-lto/bin/gcc -m32 -O2 -g -ftracer
-fsched2-use-superblocks testcase.c
testcase.c: In function ‘bar’:
testcase.c:13:1: internal compiler error: in dwarf2out_frame_debug_adjust_cfa,
at dwarf2out.c:1859
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

I don't know how much, if at all, is this related to pr41883 and pr41889
