Description Ariel Burbaickij 2022-08-23 08:29:33 UTC 
I was debugging an application under Cygwin with gdb-12.1 when following happened to gdb itself:


1048          void* __place = _Raw_bytes_alloc(__alloc).allocate(__size);
(gdb) s
__gnu_cxx::new_allocator<char>::allocate (__n=85, this=<optimized out>)
    at /usr/src/debug/gcc-11.3.0-1/x86_64-pc-cygwin/libstdc++-v3/include/ext/new_allocator.h:103
103           allocate(size_type __n, const void* = static_cast<const void*>(0))
(gdb) s
__wrap__Znwm (sz=85) at /usr/src/debug/cygwin-3.3.5-1/winsup/cygwin/libstdcxx_wrapper.cc:55
55        return (*user_data->cxx_malloc->oper_new) (sz);
(gdb) s
/cygdrive/d/a/scallywag/gdb/gdb-12.1-1.x86_64/src/gdb-12.1/gdb/infrun.c:2553: internal-error: resume_1: Assertion `pc_in_thread_step_range (pc, tp)' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.

Comment 1 Ariel Burbaickij 2022-08-23 08:31:47 UTC 
it always crashed  on the same spot repeatedly in my debugging attempts on an application.
