t/92-segv-fork.t sometimes freeze

[lzsiga]

Test script t/92-segv-fork.t randomly freezes (i.e. waits infinitely); the reason seems to be the lack of synchronization between main process and _SIG_CHLD: they work on the same data-structure (queue).
I might try to come up with some synchronization (I hope lock function will do)

Edit 2026-02-24 17:47 'lock' doesn't help in this context, but I still see two options: #1 reorganize the compelete code, #2 start another thread. I think I'll go with the second option.

Im pretty certain this is the correct issue for this report #191

and i think twata1 is reporting the previous test as its the last one with output.

I'm not sure, but perhaps a little improvement can be achieved, if _SIG_CLD calls wait4 in a loop (ie while it returns a valid pid). Also I am working on a synchronized version ( https://github.com/lzsiga/hello-world/blob/master/perl/mutex_test_02.pl )

I really appreciate the time you're taking to look at it.

@lzsiga can you try this branch? https://github.com/perl5-dbi/DBD-Oracle/tree/gh212
