  Target Milestone: ---

I see following regression/internal-error when using gdb (13.1) on Solaris =
x86:

(gdb) run -P
Starting program: /usr/bin/firefox -P
[Thread debugging using libthread_db enabled]
warning: could not convert 'mutex_t' from the host encoding (ISO-8859-1) to
UTF-32.
This normally should not happen, please file a bug report.

/builds/psumbera/userland-gdb-13/components/gdb/gdb-13.1/gdb/target.c:2641:
internal-error: target_resume: Assertion `inferior_ptid !=3D null_ptid' fai=
led.
A problem internal to GDB has been detected,
further debugging may prove unreliable.

I used git bisect and it says:
