Still here in hrev38742, also gdb will start to eat CPU after Ctrl-c.

Can I use sigint to detect the user input and exit the program?

Replying to Freeman:

Can I use sigint to detect the user input and exit the program?

I have just compared gdb behavior with my FreeBSD box - on pressing Ctrl-C it prints "Quit" in the input line and left gdb running. I suspect gdb/readline uses more sophisticated signals handling (posix signals?) and cannot be fixed by adding just another handler.

AFAIR the "tree" version of gdb/readline was ported much earlier than posix signals support was implemented in Haiku - so it can have some "forgotten" hacks and workarounds to let it work. I suggest to port actual version of gdb for Haiku separately (or check if it is alrteady available in HaikuPorter) and try to reproduce the problem. gdb is 3rd-party software and will be outsorced soon - there are no sense to bother with outdated "tree" version anyway.

Milestone: R1Unscheduled

Problem is still here in hrev48547. I tested arm-none-eabi-gdb-x86 (port of a current GDB, but without native apps debug support) and it doesn't have the problem, so porting a current version of gdb would indeed probably fix this.

Moving out of R1 milestone since we have Debugger as a viable replacement now.

GDB was outsourced and updated to a (somewhat) newer version; if this issue persists please report it at HaikuPorts.
