[syslinux] 3.73 crashes FreeDOS in VMWare - 3.72 works fine

[Axel Reinhold]

With the same configuration an ISOLINUX CD which boots a FreeDOS Floppy
image via MEMDISK Syslinux-3.73 crashes in VMWare and also on several
newer boxes just after the kernel loading with "invalid OPCODE ...".
Same CD with Syslinux-3.72 is working fine. Build environment for 3.72
was gcc-4.3.2 for 3.73 gcc-4.3.3 - any idea what can cause the troubles?
