That's busted. Seems like a preexisting issue in current master. I bisected this, and found out it was a regression introduced by this commit: 8579fd136a614985bd27f20539c7bb7c5a51287d is the first bad commit commit 8579fd136a614985bd27f20539c7bb7c5a51287d Author: Andrew Burgess Date: Mon Nov 8 14:58:46 2021 +0000 gdb/gdbsupport: make xstrprintf and xstrvprintf return a unique_ptr The motivation is to reduce the number of places where unmanaged pointers are returned from allocation type routines. All of the callers are updated. There should be no user visible changes after this commit. This commit is present in the GDB 12 branch and not in GDB 11, so it's a regression there.
