PluginDirectoryScanner crashes when it scans more than ~800 VST3 from a folder

[5amx]

Hi Juce Forum, please help me with this issue.

I’m creating a scanner that scan VST3 plugins from a folder with PluginDirectoryScanner and scanNextFile. It works well, but when I scan a folder that has a lot of VST3 files (about 800 or more) it crashes.

This is the error that is happening on file juce_VST3PluginFormat. As you can se it is related with CFBundleLoadExecutableAndReturnError.

This is what appears in console as an error:

dyld[5473]: could not create thread local variables pthread key
libc++abi: cannot create thread specific key for __cxa_get_globals()

Any guess what it can be? Thanks in advance for your kindly help!

Does it crash in Release as well as Debug? Protected plugins will crash the debugger.

Loading 800 vst3 plugins in one process might just simply have run you out of memory. Anything like that seem to be the case?

Thanks for your reply.

Unfortunately no, it crashes even in release version. I think it’s related to a memory issue that cannot handle to scan a lot of plugins. I’m checking what I can do.

I think the same, even in Release version is happening the crashing. Do you have any idea what I can modify to increase the memory involved?

So I think most folks who make reliable scanners end up realizing they have to do them out of process with a sub process that does n at a time and records the done ones. I don’t know if there’s another answer especially if some vsts have big load time footprints
