node-ibm_db: malloc error when using library

Operating System Name: latest version of MacOS Monterey, M1 chip
db2level output from clidriver if in use: unsure
Target Db2 Server Version: unsure, some version of Db2 on Cloud that was working prior to this issue
ibm_db version: 3.1.0
For non-Windows, output of below commands: uname - Darwin uname -m - arm64
Value of below environment variables if set: IBM_DB_HOME: nothing/blank PATH: /Library/Frameworks/Python.framework/Versions/3.11/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin DYLD_LIBRARY_PATH: /usr/local/lib/gcc/8:

When database code is executed with the library, I get the same error as this user: https://github.com/ibmdb/node-ibm_db/issues/888.

This was a known issue to our team previously, and we were able to get around this error, even on newly setup laptops by running rm node_modules/ibm_db/installer/clidriver/lib/libstdc++.6.dylib after running the npm install commands. However after a fresh npm install on my computer, in which this library on the same version was working previously, the file node_modules/ibm_db/installer/clidriver/lib/libstdc++.6.dylib did not exist, and I ran into this error again.

The issue has been resolved. A summary of steps taken to reach resolution

arch -x86_64 /bin/bash  -- points gcc to the x86_64 version

cp /usr/local/lib/gcc/8/libstdc++.6.dylib {path_to_application}/node_modules/ibm_db/installer/clidriver/lib

In the ~/.zshrc file:

export ARCHFLAGS="-arch x86_64"
export DYLD_LIBRARY_PATH=/usr/local/lib/gcc/8:{ABSOLUTE PATH TO MY APPLICATION THAT USES NODE_IBM_DB}/node_modules/ibm_db/installer/clidriver/lib:$DYLD_LIBRARY_PATH

Doing a fresh reinstall of ibm_db may have helped too, as opposed to doing rm -rf node_modules

npm uninstall ibm_db

npm install ibm_db

thanks again @bimalkjha
