All calls into the personality and their return when it works (first parameter of personality is ex, second is actions): ``` personality(0000000000f0f9f0, 1) _URC_CONTINUE_UNWIND personality(0000000000f0f9f0, 1) _URC_HANDLER_FOUND personality(0000000000f0f9f0, 6) _URC_INSTALL_CONTEXT personality(0000000000f0f9f0, 2) _URC_INSTALL_CONTEXT [2020-11-28 21:44:25.133 crash.exe(15248)] Deallocated! personality(0000000000f0f9f0, 2) _URC_CONTINUE_UNWIND [2020-11-28 21:44:25.135 crash.exe(15248)] Caught! ``` and on a crash: ``` personality(0000000000e603b0, 1) _URC_CONTINUE_UNWIND personality(0000000000e603b0, 1) _URC_HANDLER_FOUND personality(0000000000e603b0, 6) _URC_INSTALL_CONTEXT personality(0000000000e603b0, 2) _URC_INSTALL_CONTEXT [2020-11-28 21:45:06.703 crash.exe(12620)] Deallocated! personality(0000000000e603b0, 2) _URC_CONTINUE_UNWIND personality(0000000000e603b0, 2) _URC_INSTALL_CONTEXT personality(0000000000e603b0, 2) _URC_CONTINUE_UNWIND personality(0000000000e603b0, 2) _URC_INSTALL_CONTEXT personality(0000000000e603b0, 2) _URC_CONTINUE_UNWIND zsh: segmentation fault ./crash.exe ``` With removed `free()` (never crashes): ``` personality(0000000000f20170, 1) _URC_CONTINUE_UNWIND personality(0000000000f20170, 1) _URC_HANDLER_FOUND personality(0000000000f20170, 6) _URC_INSTALL_CONTEXT personality(0000000000f20170, 2) _URC_INSTALL_CONTEXT [2020-11-28 21:48:16.847 crash.exe(15284)] Deallocated! personality(0000000000f20170, 2) _URC_CONTINUE_UNWIND [2020-11-28 21:48:16.849 crash.exe(15284)] Caught! ``` I have no idea why there are extra ones when it crashes - that is just odd. I would expect this to behave deterministically. Time to dig into libgcc code, I suppose.
