Well, my modem did it. ;-)
Now I get this:

$ gdb eperl.exe
(gdb) run README
(gdb) up
#1  0x10064727 in Perl_vmess (my_perl=0x1026fb48, pat=0x1000be0b "panic: MUTEX_LOCK", args=0x330c4) at util.c:946
946         SV *sv = mess_alloc();
(gdb) 
#2  0x10065481 in Perl_vcroak (my_perl=0x1026fb48, pat=0x1000be0b "panic: MUTEX_LOCK", args=0x330c4) at util.c:1146
1146            msv = vmess(pat, args);
(gdb) 
#3  0x10065abf in Perl_croak_nocontext (pat=0x1000be0b "panic: MUTEX_LOCK") at util.c:1216
1216        vcroak(pat, &args);
(gdb) 
#4  0x1000c13d in Perl_malloc (nbytes=1008) at malloc.c:1558
1558    }
(gdb) 
#5  0x1008072c in S_more_sv (my_perl=0x1026fb48) at sv.c:310
310             New(704,chunk,1008,char);   /* Safefree() in sv_free_arenas()     */
(gdb) 
#6  0x1008e20b in Perl_newSVpvn (my_perl=0x1026fb48, s=0x10064450 "", len=0) at sv.c:6806
6806    }
(gdb) 
#7  0x100644f8 in S_mess_alloc (my_perl=0x1026fb48) at util.c:819
819             return sv_2mortal(newSVpvn("",0));


Err. Unfortunately, I know literally nothing about gdb, malloc, or
mutex, so ... what kind of diagnosis should I try and perform? %-)
