Segmentation Fault on linux

[Yuji Takenobu]

I am using crossvcl for linux (RHEL7.6), and suceeded to compile delphi code and got shared library (.so) with libcrossvcl.so, but when I load the shared library via the python library ctypes.CDLL I got segmentation fault. Even if I tried gdb command to see the error, I could not get useful information. Do you have any idea to solve this issue?

‌

(gdb) run

warning: Probes-based dynamic linker interface failed.
Reverting to original interface.

Program received signal SIGSEGV, Segmentation fault.
