Source: emacs
Version: 1:29.4+1-5
Severity: normal

Dear maintainers,
Compiling the emacs failed for loong64 in the Debian Package
Auto-Building environment.
The error log is as follows,
```
......
../src/bootstrap-emacs(FletX+0x17c) [0x555556382fec]
../src/bootstrap-emacs(eval_sub+0x958) [0x55555637efd8]
...
make[5]: *** [Makefile:282:
/<<PKGBUILDDIR>>/debian/build-src/lisp/emacs-lisp/seq.elc] Segmentation
fault
make[4]: *** [Makefile:841:
/<<PKGBUILDDIR>>/debian/build-src/lisp/emacs-lisp/seq.elc] Error 2
make[4]: *** Waiting for unfinished jobs....
......
```
The full build log can be found at
https://buildd.debian.org/status/logs.php?pkg=emacs&ver=1%3A29.4%2B1-5&arch=loong64.
The binary emacs-common blocks the build of 21 source packages.
Referring to other architectures, it is recommended that do not try to
build with native compilation on loong64, too.
Please consider the patch I attached.
Based on the attached patch, emacs 1:29.4+1-5 was built successfully on
local ENV.
