uClibc is doing this nearly since the beginning (commit
f91e94f6c5a1f1d6dfd3e5a535df303b805bf321 in 2001). I think normally this is
okay, because uClibc tries to be compatible to glibc. There are cornercases
like this issue. I think the patch is useful and should be applied.

Hi,

following compile error occurs for Buildroot targeting sh4-linux-gnu for the
e2fsprogs package:

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
