So far I can see the problem:
writev(2, [{iov_base="free(): invalid pointer", iov_len=23}, {iov_base="\n",
iov_len=1}], 2) = 24
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x7ff86861c000
rt_sigprocmask(SIG_UNBLOCK, [ABRT], NULL, 8) = 0
gettid()                                = 11585
getpid()                                = 11585
tgkill(11585, 11585, SIGABRT)           = 0
--- SIGABRT {si_signo=SIGABRT, si_code=SI_TKILL, si_pid=11585, si_uid=1000} ---
+++ killed by SIGABRT (core dumped) +++

You need to install audacity-debuginfo and audacity-debugsource with a version
and release number that matches the audacity that you have installed.
Then execute "gdb audacity", in gdb enter "r" and after the sigabort happens
type bt full and copy paste it into a file and attach it.

This will hopefully show what is different on the computers that crash.

I think at this stage you need to switch to:
https://download.opensuse.org/repositories/home:/plater/Tumbleweed
for audacity and debug packages.
Only thing that I've been doing differently to upstream since v3.0.1 is using
wxWidgets built with gtk3 but I'll wait for the gdb backtrace before I try
wxWidget gtk2. Audacity, after it switched wxWidgets from 3.0x to 3.2x it
wouldn't run properly with gtk2
