/home/gerald/gcc-ref12-amd64/bin/gcc> jcparam.i -O2 -g
during GIMPLE pass: dse
jcparam.c: In function ‘jpeg_simple_progression’:
jcparam.c:514:1: internal compiler error: Segmentation fault
514 | jpeg_simple_progression (j_compress_ptr cinfo)
| ^~~~~~~~~~~~~~~~~~~~~~~
0x829785baf handle_signal
/usr/src/lib/libthr/thread/thr_sig.c:248
0x82978516e thr_sighandler
/usr/src/lib/libthr/thread/thr_sig.c:191
If I use -O1 instead of -O2 or omit -g the ICE goes away.
