GCC hangs (never completes) with test case using -frtl-abstract-sequences.
Command line:
avr-gcc -mmcu=atmega169 -Os -frtl-abstract-sequences -c test.c -o test.o
The test case fails with -O[23s], but is successful with -O[01].

I've reduced the test case to the smallest that I could get to. Note that when
the showtext() function call is replaced by its contents, the test case passed
for -Os. Also, pgm_read_word() in the C test case is a macro (from the avr-libc
library) that generates inline assembly.

This is most likely a dup of bug 33009.

The patch in bug #33009 does indeed fix the problem that I'm seeing. Closing
bug as duplicate of #33009.
