SIGSEGV on ARMv7 upon loading dynamic library #14906
Description
System information (version)
- OpenCV => 4.1.0 (master b95e93c)
- Operating System / Platform => Android 7.0 armeabi-v7a (Samsung Galaxy J5 Pro)
- Compiler => Android NDK 20
Detailed description
I am using the static libraries to produce a dynamic library which is then used by an Android app.
Upon first calling into my dynamic library, I experience the following crash (some information removed):

The app works fine on other architectures.
Steps to reproduce
Load a dynamic library (.so) that links against the OpenCV static libraries for armeabi-v7a.
