I could reproduce a crash like in commen 11 and 13 with the current FDM 3.9.7 build 1641 download, or 3.9.2 build 1303.
But it is just visible up to wine-1.5.20. Commit d6c0e8159 modifies InternetCrackUrl, so FDM no longer triggers the crash.
The crash seems to happen because nScheme is set to INTERNET_SCHEME_UNKNOWN, which causes INTERNET_GetSchemeString to return NULL, which gets dereferenced in calc_url_length by strlenW.
Following merge requests attempts to avoid this crash: https://gitlab.winehq.org/wine/wine/-/merge_requests/5069
Attached files contains some more notes on the debugging.
The crash observed in comment 15 with wine 1.7.54 might have another reason.
