crash, latest beta cvs, progress bar

i'm assuming this is another progress bar/gutter crash have not seen this one before. i cvs'd this afternoon, and ran vm ok for a few hours. then i tried enabling font-lock in my summary buffer. worked ok at first. though the progress bar acts very weird. seems like before it slowly progressed as the buffer was fontified. now it zips back and forth madly, almost like it is progressing for each line or maybe each regexp. anyone it looks like it's outta control. well, i did a "get new mail" at one point and it spewed out ahuge backtrace which completely overran my xterm..... it may not have been helpful anyhow since this particular xemacs was compiled with no debugging info and optimized. well, i've got some of it, but i doubt it's useful... appended to the end. here is a gdb
