C test case from gcc.target/avr/torture

I see this ICE with current compiler from master with an avr test case:

$ avr-gcc -g -O3 -std=3Dgnu99 -mmcu=3Datmega128 pr109907-2.c -S

The ICE goes away when I remove the -g switch.

Target: avr
Configured with: ../../source/gcc-master/configure --target=3Davr --disable=
-nls
--with-dwarf2 --with-gnu-as --with-gnu-ld --disable-shared
--with-fixed-point=3Dno --with-long-double=3D64 --enable-languages=3Dc,c++
Thread model: single
Supported LTO compression algorithms: zlib
gcc version 14.0.1 20240118 (experimental) (GCC)=
