HANG ripgrep statically linked with musl hangs when run under DR

[philramsey-arm]

Describe the bug
Running ripgrep (rg) statically linked with musl under DR results in an application hang.

To Reproduce
On Ubuntu 24 Graviton 4:
curl --location --remote-name https://github.com/BurntSushi/ripgrep/releases/download/15.2.0/ripgrep-15.2.0-aarch64-unknown-linux-musl.tar.gz

tar -xf ripgrep-15.2.0-aarch64-unknown-linux-musl.tar.gz

sudo install -m 0755 ripgrep-15.2.0-aarch64-unknown-linux-musl/rg /usr/local/bin/rg

drrun rg "text pattern"

• What happens when you run without any client?
  I am not using a client.
• What happens when you run with debug build ("-debug" flag to drrun/drconfig/drinject)?
  The behaviour is the same with a release or debug build.

The call stack is not useful:

(gdb) bt
#0 0x00000000489d9d08 in ?? ()
#1 0x0000fffdf6cff0f0 in ?? ()
Backtrace stopped: not enough registers or memory available to unwind further

Expected behavior
I expect ripgrep to finish running as normal.
