Bug ID: 122066
Summary: [m68k] internal compiler error: in
print_operand_address, at config/m68k/m68k.cc:5259
Product: gcc
Version: 15.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org

Target Milestone: ---
Host: m68k-*-*
Trying to build the x265 package in Debian unstable on m68k leads to an
internal compiler error early in the build:

Please submit a full bug report, with preprocessed source (by using
-freport-bug).
Please include the complete backtrace with any bug report.
See <file:///usr/share/doc/gcc-15/README.Bugs> for instructions.
Preprocessed source stored into /tmp/ccuMm0xN.out file, please attach this to
your bugreport.
The full build log is available in:
https://buildd.debian.org/status/fetch.php?pkg=x265&arch=m68k&ver=4.1-3&stamp=1758879097&raw=0
It also contains the pre-processed source which can be extracted to reproduce
the problem. The same ICE was also observed in PR target/98262, so I'm not sure
whether this is the same bug.
