Bug 20886 – std.process.browse does not work with URLs 256 characters or longer

Manjaro/Arch x86_64, dmd 2.092.0. Supplying a long URL to std.process.browse seems to just make it execute xdg-open without passing the URL as an argument. (The URL I want to open is 397 characters.) import std; void main() { immutable url = "http://" ~ 'x'.repeat(249).array.idup; assert(url.length == 256); browse(url); } No browser window is opened, instead it outputs: > xdg-open -- opens a file or URL in the user's preferred > application > > Synopsis > > xdg-open { file | URL } > > xdg-open { --help | --manual | --version } > > Use 'man xdg-open' or 'xdg-open --manual' for additional info.

I ran into this issue and it seems that is something wrong with this line > args[1] = = url.tempCString(); because after that line args[1] is ""

@MoonlightSentinel created dlang/phobos pull request #7988 "Fix 20886 - Retain tempCString buffer in browse" fixing this issue: - Fix 20886 - Retain tempCString buffer in browse The temporary buffer returned by `tempCString` was assigned to a `char*` and hence destroyed after the statement. This worked by accident for small URL's because the space was allocated on the stack and not overwritten before forking. https://github.com/dlang/phobos/pull/7988
