The QVarLengthArray inside qlocale_blackberry.cpp was being preallocated with
512 bytes, that means internally it could grow up to 512 bytes using the
stack before switching to the heap, but its actual semantic size was still 0.
After qt_safe_read(... buffer.data() ...) was being called, data was written
to the QVarLengthArray buffer, but its semantic size was still 0, since it was
not resized or anything. This triggered an assertion when buffer[bytes] = '\0'
was assigned, since 'bytes' > buffer.size() ( == 0) despite buffer.capacity()
== 512.
