Please submit a full bug report, with preprocessed source (by using
-freport-bug).
Please include the complete backtrace with any bug report.
Attached is the preprocessed rw_bitmaps.c file.
The problem exist only for -O1/-O2/-O3, using -Os/O0 does not trigger the ICE.
And it is an new issue in gcc 13.2.0, it does not happen for 12.3.0.
Do you need more information, do not hesitate to ask.
best regards
Waldemar
