Dump a process without running first

[kasperk81]

ciru dump -- <command>, my process crashes immediately so it's not feasible to trace it with pid and potentially lose vital information at the startup.

Can you elaborate your problem in more details ?

[kasperk81]

ciru can dump the running process using pid. ciru dump <PID>, which is similar to gdb -p <PID>

i am looking for the other option as well where ciru would run the user command by itself and wait until it crashes before collecting the dump, so it doesn't miss anything at the app startup in the dumps, akin to gdb -- <command and its args>.

my app crashes in first few milliseconds, so it is not very convenient to pause the app, get its pid and feed it to ciru.
