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

(gdb)

1146            msv = vmess(pat, args);

(gdb)

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