Thanks for that. mozilla-1.3.1,2 compiles and installs successfully. Unfortunately, it doesn't run. I get an unaligned access report, followed by a segmentation violation: pid 49966 (mozilla-bin): unaligned access: va=0x160bbb2df pc=0x160b9db2c ra=0x16200e8ac op=ldq (gdb) where #0 0x160b9eaa000 in ?? () #1 0x160b9db30 in nsPref::GetDefaultIntPref(char const*, int*) () from /usr/X11R6/lib/mozilla/components/libpref.so #2 0x160b9db30 in nsPref::GetDefaultIntPref(char const*, int*) () from /usr/X11R6/lib/mozilla/components/libpref.so Error accessing memory address 0x10: Bad address. (gdb) Suspiciously, the address looks like it is shifted 8-bits left, which is consistent with the unaligned access being one byte below an aligned address. This looks like an out-by-one error somewhere. I'll try re-compiling with the defaults (rather than for ev56) and see if this is just a gcc bug (as I suspect). BTW, has anyone else noted problems debugging processes when there is other system activity? (5.1-RELEASE on a 4-CPU AS4100) On several occasions I've had gdb go to sleep - it won't respond to QUIT, STOP or INTR from the keyboard but it can be killed from another process. When it gets into this state, ps shows: 204 54592 54584 108 8 0 37384 37144 wait I p2 0:14.78 /usr/bin/gdb 204 54593 54592 72 105 0 36184 26912 - TX+ p2 0:04.36 /usr/X11R6/l Peter
