Hi,
I'm wondering if shared libraries (on Linux) support call exported function
from multiple threads. I made small demo. Threads send JSON PChar into
shared lib function which parse it and log in syslog. No global vars,
everything locally in function. But even that I'm getting random errors

I've used it in multi-threaded apache modules.

Perfect, I have now all the arguments to defend the "Dinosaur Threading"choice.
Thanks.
I'd second Charlie's point, and add that a very small change to a
system's layout, e.g. a DIMM on a NUMA node going dodgy and being
excluded
Huh, sorry to come back with this but...
Loadlibrary() for a sub-dependency works. ;-)
For example:
libopusfile.so has libopus.so as dependency.
So, before to loadlibrary(libopusfile.so), do --> loadlibrary(libopus.so),
keeping the original file-name.
Example:

Well it doesn't work or fpjson module is not thread safe in this case. You
can test it by

Hello,
1 - What happens if my constructor raise an exception? Is my destructor
automatically called?
2 - Are the class fields automatically initialized to Default(T) just like
in Delphi?

Sadly, on Wndows 10 I've got "Runtime Error!", when closing the program.
The dll is working but this appends if libgcc_s_dw2-1.dll is static or

This is the message after closing the error-panel:

Hello,
I'm writing a function protected by a critical section which can have
recursive calls under certain conditions.

section, if my thread make 6 additional calls to TCriticalSection.Enter, to
release the critical section my
