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)

argument)

EINVAL (Invalid argument)

write(2, "The assertion realpath(s,o) on l"..., 91) = 91

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)
