I received no reply on this question at questions mailing list, so I try asking this here. Hope I'm not asking this in completely wrong list. In recent discussion in OpenWatcom lists it was noticed that at least certain addressing modes of assembler ENTER instruction causes a crash when used in Linux. GCC circumnavigates this by not emitting ENTER instructions in machine code. Linus's comment on the above issue can be found on: http://groups.google.co.nz/groups?selm=7i86ni%24b7n%241%40palladium.transmeta.com What's the status of the above "feature" in FreeBSD, does the kernel support the whole x86 instruction set without similar cut corners? -Reko
