8 years ago hmmm, looks like pcre is crapping out. Everything is working fine for me on 10.10.5, so a bit hard for me to trace.
Can you confirm that this crash is consistent ... same place every time?
Also, are you running from the 0.6.0 release, or from head?

8 years ago This problem was with git head. Crashed the same place every time.
I forgot that I had built extempore with
cmake -DCMAKE_BUILD_TYPE=Debug ..After changing the configuration back to default with cmake .. the problem went away.
What is the recommended way to debug extempore?

8 years ago @neilt yep, using -DCMAKE_BUILD_TYPE=Debug is the recommended way to debug, but it's always worth doing a make clean && make clean_aot first.
Are you still seeing the problem?
I've also just bumped PCRE to 8.38, although I'm not sure whether that'll help.

8 years ago Yes I did make clean and make clean_aot first.
After cleaning, then updating to git head still seeing the problem in the Debug build and seems to work fine in Release build . I also tried by deleting cmake-build and retrying everything, same result. The line numbers are slightly different but the pattern is the same. I can post another crash log if necessary.
The same problem (crashes right after logging NoteInitData >>> <i64,SAMPLE,SAMPLE,i64,i64,i64,i64,SAMPLE>) also arises with make aot in Debug build.

We have seen some pcre related problems before, so I do have some concerns about this. I'll try to find time to take a look next week.

4 years ago I'm assuming this specific issue is no longer troubling you, but if you do run into new macOS compilation errors then do let me know - especially now that we've got proper cross-platform CI tests :)
