I think you tried it on IA32? So X64 arch requires /wd4204 /wd4244 /wd4090 /wd4334 and IA32 doesn't need /wd4334. I will have separate build options for each.

I think you were saying the string functions such as strtol, strtoll and etc. It has been a while, this was came with Redfish POC code v4 released by Intel in 2018 to HPE. However those are from edk2-lib as fa as I can tell.
I can say something in the file header.

Ah, you were talking about the missing characters last time. jansson only uses (v)snprintf for the error and dump messages but not using on the JSON object operation. And libredfish doesn’t use these two functions fortunately.
Do you think we should parse the formatting string and replace %s with %a? Or any other suggestions?
