Public bug reported:
Hi,
I have isolated a testcase from the GCC testsuite (actually gfortran,
test proc_ptr_51.f90) which produces tons of:
qemu-arm: /home/christophe.lyon/src/qemu/accel/tcg/cpu-exec.c:701:
cpu_exec: Assertion `!have_mmap_lock()' failed.
including with master qemu as of today.
I'm attaching a tarball containing:
qemu-assert:
cmd lib proc_ptr_51.exe
qemu-assert/lib:
ld-linux-armhf.so.3 libc.so.6 libgcc_s.so.1 libgfortran.so.5 libm.so.6
where cmd is the basic command used to launch the test & reproduce the
failure.
Note that the test or the generated may actually be buggy: I have
reported failures on native aarch64 and arm machines. Yet, qemu should
not fail with a loop of asserts.
** Affects: qemu
Importance: Undecided
Status: New
