Description:

Sorry this is for the soon to be unsupported i686 version. But I'm not buying a new desktop machine just for you :-)

Hit this after most recent pacman -Suy. Seamonkey then dies with an Illegal Instruction and coredump. The coredump backtrace shows it's thrown in libfreeblpriv3.so, which is part of nss.
The version of nss in use at the time was 3.32-1.
Downgrading to my previous version 3.31-3 cured the problem.

Additional info:
* package version(s)
* config and/or log files etc.


Steps to reproduce:

Steps to reproduce:
Start seamonkey from a command window on an i686 system - mine uses LXDE. It asks for my master password (I suspect this needs to be configured, given where it blows up), and then dies with an Illegal Instruction exception.

Other info:
Here's the traceback from the coredump.

Using host libthread_db library "/usr/lib/libthread_db.so.1".
backtraceCore was generated by `seamonkey'.
Program terminated with signal SIGILL, Illegal instruction.

NSS requires SSE2. Does your CPU support SSE2?
Comment by Paul Gover (goverp) - Friday, 22 September 2017, 19:46 GMT
No, it's a Pentium III, and only does SSE. But that doesn't explain why seamonkey's worked for the last 10 years or thereabouts!
Comment by Jan Alexander Steffens (heftig) - Friday, 22 September 2017, 20:05 GMT
The requirements on NSS changed.

Please test 3.33-2 which is in testing. You can install the package on its own, it was built in extra-i686/extra-x86_64 chroot.
Comment by Paul Gover (goverp) - Friday, 06 October 2017, 10:04 GMT
Thanks muchly.

Can't test for about a week, as I'm on holiday away from the offensive machine.
