i386 ddb trace stopped working with gcc48

["J. Hannken-Illjes" <hannken%eis.cs.tu-bs.de@localhost>]

Since i386 switched to gcc48 ddb trace no longer works:

fatal breakpoint trap in supervisor mode
trap type 1 code 0 eip c02802f4 cs 8 eflags 202 cr2 bbbab0c4 ilevel 8 esp 800
curlwp 0xc5a9fd20 pid 0 lid 2 lowest kstack 0xdd3b22c0
Stopped in pid 0.2 (system) at  netbsd:breakpoint+0x4:  popl    %ebp
db{0}> bt
breakpoint(c0e661c0,3f8,0,0,c61c5158,c170dacc,c6188000,c5f396c0,c5f39748,dd3b4edc)
 at netbsd:breakpoint+0x4

Thats all, never get more than one line.
The i386_frame from %ebp = dd25ef30 looks like:

dd25ef30:       7ff             <= should be the previous frame
dd25ef34:       c0277cc1        <= comintr+0x53e (caller of breakpoint)
dd25ef38:       c0e661c0

Ideas anyone?
