Thanks to Thomas Leitner <tom_at_finwds01.tu-graz.ac.at> for his quick response:

Original question:

>> This one comes from some people I know who are porting code to an Alpha
>> running DU ..
>>
>> It seems they are having problems with gcc (off the freeware CD) and dbx.
>> dbx seems to cause the Alpha to crash with an illegal op-code.
>>
>> Before I start squirelling through what they're doing, is anyone aware
>> of any hiccups with dbx and gcc on 4.0b? I thought I'd ask first (rather
>> than find out later).

I checked the archive, and found this from April:

the number and speed of feedback mails! All unanimously said that there is
a bug in Digital Unix 4.0B, where normal user dbx sessions can hang or
crash the system (bad bug, isn't i
