Test test_malloc_used_by_lib sometimes fails on FreeBSD i386 #1967
Description
Hi,
After having fixed several tests on FreeBSD (see #1945 and #1950), a tests still fails sometimes on FreeBSD 15.0-RELEASE i386 (32 bit).
Call 1 :

Do you need "set solib-search-path" or "set sysroot"?

Continuing.

Thread 2 received signal SIGABRT, Aborted.
Sent by thr_kill() from pid 44942 and user 0.
0x2077cd5f in thr_kill () from /lib/libc.so.7
Assertion failed, so the test is aborted. When the test succeeds, I get a non-NULL value for __a_value above.
Here is the backtrace just after a failure :
