node-ibm_db: Driver Issue with MacOS Monterey (not fault of node-ibm_db)

Hi, I don’t know if this is an issue with node-ibm_db and Monterey or if it is a db2 driver issue. If it is a driver issue, do you know where can I report it?

Problem description Whenever I execute the .open() method with a connection string nodejs fails with the following message

node(8732,0x700006e3c000) malloc: *** error for object 0x7ffb4e817e00: pointer being freed was not allocated
node(8732,0x700006e3c000) malloc: *** set a breakpoint in malloc_error_break to debug

This happens even with the latest version of the package and freshly installed drivers.

Environment

The node version used is v14.18.1 (freshly installed from nvm)
Intel Macbook Pro 16
MacOS 12.0.1
GCC: Apple clang version 13.0.0 (clang-1300.0.29.3)

@cpibm After your latest update, I think the issue got resolved due to installation of g++ and by looking on this stack again, the issue seems with the libstdc++.6.dylib library which is under ibm_db\installer\clidriver\lib directory. So, deleting ibm_db\installer\clidriver\lib\libstdc++.6.dylib should fix the issue. This libstdc++.6.dylib library seems older and not compatible with Monterey. When you installed g++, it installed libstdc++.6.dylib too and with your workaround, systems libstdc++.6.dylib is getting effective. Running otool -L libdb2.dylib should give info about from where libstdc++.6.dylib is getting picked up. So, you can delete or rename clidriver\lib\libstdc++.6.dylib post installation of ibm_db and run your test program. Thanks.

That did it 🥳 ! deleting the libstdc++.6.dylib library from ibm_db\installer\clidriver\lib fixes the issue. Thanks a lot for your help

Ok, this works, but does the mean we have to do this now each time ? or will there be some fix somewhere (in mac ? node ? or ibm_db ? ) thanks

@huineng @vuldin Removed clidriver\lib\libstdc++.6.dylib from clidriver. So, there should not be any issue for new installation now and below process should fix the issue for existing installation:

uninstall ibm_db and reinstall it. OR,
rm -rf ibm_db\installer\clidriver; cd ibm_db; npm install Thanks.
