memory leak 21.5.b16 / Solaris "10" (5.10) / gtk / S1SCC
Hi all,
found a slight problem tonight -- seems to be a gc-related
memory leak in 21.5.b16:
$ /usr/ucb/ps -auxwww |grep xemacs
USER PID %CPU %MEM SZ RSS TT S START TIME COMMAND
jmcp 17583 0.0 58.9968632600680 ? T Jan 06 11:18

Once gcore of 17583 had finished (20mins later!) I ran
dbx over it:
espresso:jmcp $ dbx /d00/xemacs/bin/xemacs-21.5-b16 /home/jmcp/core.17583

To remove this message, put `dbxenv suppress_startup_message 7.1' in
your .dbxrc

which doesn't tell _me_ much but it might (I hope) help you.
