It's on a pre-8.2 LFS/BLFS, that is: SVN-20180209 for LFS, and around the same for BLFS. I have the same config as you, but I had removed the extra CFLAGS. When putting them back, no more crash (on this site at least). Guess what? I've done all my testing with 2.49.1... The directory https://archive.mozilla.org/pub/seamonkey/releases/2.49.2 does not contain a "source" subdirectory, so I assumed that the latest version was 2.49.1, and I did not check the book! What a shame... Looks like the currency script should check that there is a "source" subdirectory. Presently, there are only "update" and "win32" subdirectories, which seem to contain only binary builds. But it's not an excuse for my errors...

But how can I make sure that it works? Pointer to the mailing list maybe, or direct advice. Thanks for your answers. IIRC, we disabled cairo to be consistent with firefox. I do not recall the problematic pages, but I think it may have been menu appearance on all pages. Looking at my logs, the last time I enabled cairo in SM was seamonkey-2.35. I didn't build every version, but it was disabled in seamonkey-2.38. You might want to look at the optimize setting also. Do we still need -O2? Also, with only required and recommended dependencies (that is only alsa and no pulseaudio) of seamonkey, I can see html5 video (youtube), but I get no sound, although "speaker-test" and "aplay /usr/share/sounds/Front_Left.wav" both run OK. Maybe the config file is missing --enable-alsa... But maybe we should switch to require pulseaudio, as on the firefox page. Thoughts? I had pulse disabled in seamonkey-2.40, but enabled after that. There definately is an option --enable-alsa in SM, so you might want to try that. I added --enable-alsa, and I got sound. I think I'll try pulseaudio now. Large parts of the seamonkey code are based upon firefox-52.0.4-ESR, and Firefox upstream recommend pulseaudio. As of -O2, our firefox config file has it too, and says optimizing for size is broken in gcc 7, whatever that means... BTW, I have removed the extra CFLAGS, they seem to not be needed anymore. I haven't seen any crash yet, so I think system cairo is OK.
