Mac crash on quit with CORE 0.8.1 - Rick Johnson - 11-27-2022
I'm finding an issue with plugins compiled with CORE 0.8.1 that seems to affect only Mac plugins, and only ones with flyout menus. It's not limited to AI 27, and only happens about a third of the time, just after ~Plugin(). I'll summarize the crash report.
PHP Code:
Exception Type: EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: EXC_I386_GPFLT
Exception Note: EXC_CORPSE_NOTIFY
Termination Signal: Segmentation fault: 11
Termination Reason: Namespace SIGNAL, Code 0xb
Terminating Process: exc handler [28001]
Thread 0 Crashed:: Dispatch queue: com.apple.main-thread
0 libc++abi.dylib 0x00007fff204ceba7 __dynamic_cast + 26
1 com.rj-graffix.plugin.grodyplugin0x000000018dc08ca4 hdi::core::Flyout::~Flyout() + 212
I can't destroy flyouts at shutdown as with regular menus, so I tried clearing the entries, and that doesn't help. Panels are destroyed.
Here's how I define my flyout menus.
Code:
this->xFlyoutMenu.pushEntry( hdi::core::PopupEntry(
"showTTS",
"Show settings",
NULL,
true
));
this->xFlyoutMenu.pushEntry( hdi::core::PopupEntry(
"apply2projection",
"Apply to Projection panel",
NULL,
true
));
this->xFlyoutMenu.setSelectionMadeCallback (HDI_CORE_CALLBACK(axo::Plugin, this, __xFlyoutMenuCB));
this->__xformPanel.setFlyoutMenu(this->xFlyoutMenu);What's puzzling is that these crashes don't happen in Windows, and didn't happen prior to CORE 0.8.1. I'm using Xcode 10.3 and Xcode 12.4 with macOS 11.7.1 Big Sur. Any suggestions for narrowing the bug down would be much appreciated.

I took the current code and ported it back to CORE 0.8.0 (changed entry and keypress) and compiled for Mac 2020: no crashing at all, where 0.8.1 projects almost always crashed.
I'll try to build a project with the Skeleton sample that demonstrates this.

I believe I solved the problem: Don't declare a flyout menu as a class member. Instead, declare it locally and if you need to enable/disable an item or change an item's text, access it through its panel.
Code:
std::vector< std::shared_ptr<hdi::core::PopupEntry>> flyoutEntriesV = *this->__drawSettingsPanel.flyoutMenu()->entries();
flyoutEntriesV[3]->setEnabled(HDI_CORE_ILLUSTRATOR->documentCount() > 0);
