[Qemu-devel] [Bug 1776478] Re: Getting qemu: uncaught target signal 6 when running lv2 plugin cross-compilation

Thanks for the repro case; it's on my list of things to look at, but the
gating factor there is that my todo list is several miles long. If you
want to look at it yourself, the first step is probably to run the
program under qemu with qemu's -g option to enable the gdbstub, connect
an arm-aware gdb to it and see if you can get a backtrace out of it.

Getting qemu: uncaught target signal 6 when running lv2 plugin cross-
Status in QEMU:
I am part of the Zynthian team and we use qemu-arm-static to cross compile
lv2 audio plugins.
When running a compilation of DISTRHO-Ports we get:
lv2_ttl_generator: pthread_mutex_lock.c:81: __pthread_mutex_lock: Assertion
`mutex->__data.__owner == 0' failed.
qemu: uncaught target signal 6 (Aborted) - core dumped

lv2_ttl_generator source is here:
The command that is ruining is
And ./TAL-Filter-2.so source is here:
Is there a way to debug what is going on?
This runs fine on a Raspberrypi which is armv7
A workaround would also help.
