Thanks for testing glibc 2.33. This is actually a bug in gcl, triggered
by a change in glibc 2.33. It has already been reported upstream with a
patch:

Bug#995323: libc6: 2.33-0experimental2 breaks maxima

[Andreas Kloeckner]

Package: libc6
Version: 2.33-0experimental2
Severity: normal

Dear Maintainer,

Upgrading libc6 to 2.33-0experimental2  causes maxima to fail at startup
with the message:

The assertion realpath(s,o) on line 475 of main.c in function mbin failed: 
Invalid argument[1]468085 abort (core dumped)  maxima

To reproduce, simply 'apt install maxima' (version 5.44.0-3) and run
'maxima'.

Strace reveals the apparent difference in behavior:

Bad:

readlink("/proc", 0x7ffdac5d2c00, 1023) = -1 EINVAL (Invalid argument)
readlink("/proc/self", "468544", 1023)  = 6
readlink("/proc/468544", 0x7ffdac5d2c00, 1023) = -1 EINVAL (Invalid argument)
readlink("/proc/468544/exe", "/usr/lib/maxima/5.44.0/binary-gc"..., 1023) = 40
readlink("/usr", 0x7ffdac5d2c00, 1023)  = -1 EINVAL (Invalid argument)
readlink("/usr/lib", 0x7ffdac5d2c00, 1023) = -1 EINVAL (Invalid argument)
readlink("/usr/lib/maxima", 0x7ffdac5d2c00, 1023) = -1 EINVAL (Invalid argument)
readlink("/usr/lib/maxima/5.44.0", 0x7ffdac5d2c00, 1023) = -1 EINVAL (Invalid 
argument)
readlink("/usr/lib/maxima/5.44.0/binary-gcl", 0x7ffdac5d2c00, 1023) = -1 EINVAL 
(Invalid argument)
readlink("/usr/lib/maxima/5.44.0/binary-gcl/maxima", 0x7ffdac5d2c00, 1023) = -1 
EINVAL (Invalid argument)
brk(NULL)   = 0x3b89000
write(2, "The assertion realpath(s,o) on l"..., 91) = 91
rt_sigprocmask(SIG_UNBLOCK, [ABRT], NULL, 8) = 0

Good (lib6 2.32):

readlink("/proc/self", "6410", 4095)= 4
lstat("/proc/6410", {st_mode=S_IFDIR|0555, st_size=0, ...}) = 0
lstat("/proc/6410/exe", {st_mode=S_IFLNK|0777, st_size=0, ...}) = 0
readlink("/proc/6410/exe", "/usr/lib/maxima/5.44.0/binary-gc"..., 4095) = 40
lstat("/usr", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat("/usr/lib", {st_mode=S_IFDIR|0755, st_size=16384, ...}) = 0
lstat("/usr/lib/maxima", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat("/usr/lib/maxima/5.44.0", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat("/usr/lib/maxima/5.44.0/binary-gcl", {st_mode=S_IFDIR|0755, st_size=4096, 
...}) = 0
lstat("/usr/lib/maxima/5.44.0/binary-gcl/maxima", {st_mode=S_IFREG|0755, 
st_size=53250416, ...}) = 0
(continues as normal)
