Severity: important

Dear Maintainer,
I'm running into a segmentation fault while fixing locales on a
mmdebstrap'd Bullseye chroot and a 'bad address' failure when trying to
build 'wayland' inside it.
Both operations complete without error when using proot 5.3.1 from:

Hello Charles,
I tried to collect some more information, at least for the segfault.
The crash could be more isolated to this:
# proot -q qemu-i386 -S debian-i386 su -
# localedef -i en_US -c -f UTF-8 -A /usr/share/locale/locale.alias en_US.UTF-8
Segmentation fault
Adding a "catchsegv" to the command gives several different outputs like:
# catchsegv localedef -i en_US -c -f UTF-8 -A /usr/share/locale/locale.alias en_US.UTF-8
localedef: malloc.c:2539: sysmalloc: Assertion `(old_top == initial_top (av) && old_size == 0) || ((unsigned long) (old_size) >= MINSIZE && prev_inuse (old_top) && ((unsigned long) old_end & (pagesize - 1)) == 0)' failed.
Aborted
*** Segmentation fault
...
# catchsegv localedef -i en_US -c -f UTF-8 -A /usr/share/locale/locale.alias en_US.UTF-8
Bus error
*** Segmentation fault
...
# catchsegv localedef -i en_US -c -f UTF-8 -A /usr/share/locale/locale.alias en_US.UTF-8
Segmentation fault
*** Segmentation fault
Sometimes also with a backtrace like below,
also when running a rebuilt localedef with intact debug information.
When disabling address layout randomization,
with 'echo 0 > /proc/sys/kernel/randomize_va_space',
the crash can still be observed.
Unfortunately I found no other hint how to further debug this below proot.
Kind regards,
Bernhard

I tried to collect some more information, at least for the segfault.
The crash could be more isolated to this:
# proot -q qemu-i386 -S debian-i386 su -
# localedef -i en_US -c -f UTF-8 -A /usr/share/locale/locale.alias en_US.UTF-8
Segmentation fault
Adding a "catchsegv" to the command gives several different outputs like:
# catchsegv localedef -i en_US -c -f UTF-8 -A /usr/share/locale/locale.alias en_US.UTF-8
localedef: malloc.c:2539: sysmalloc: Assertion `(old_top == initial_top (av) && old_size == 0) || ((unsigned long) (old_size) >= MINSIZE && prev_inuse (old_top) && ((unsigned long) old_end & (pagesize - 1)) == 0)' failed.
Aborted
*** Segmentation fault
...
# catchsegv localedef -i en_US -c -f UTF-8 -A /usr/share/locale/locale.alias en_US.UTF-8
Bus error
*** Segmentation fault
...
# catchsegv localedef -i en_US -c -f UTF-8 -A /usr/share/locale/locale.alias en_US.UTF-8
Segmentation fault
*** Segmentation fault
Sometimes also with a backtrace like below,
also when running a rebuilt localedef with intact debug information.
When disabling address layout randomization,
with 'echo 0 > /proc/sys/kernel/randomize_va_space',
the crash can still be observed.
Unfortunately I found no other hint how to further debug this below proot.
Kind regards,
Bernhard

Dear Maintainer,
just a small addition to my mail from yesterday.
The current downstream version 5.1.0 is more or less from 2015.
And because current upstream version 5.3.0 is not showing this issue,
it might be worth considering to "just" update the debian package.
Kind regards,
Bernhard
