I've tested with several combinations of page size and export resolution, using Atlas or not, and the pattern is always the same. It seems that when the memory required is below 1500 MB, everything runs smoothly. When memory required is somewhat above 1500 MB, QGIS crashes.

QGIS 2.18 seems to support a few more memory requirement without crash. Above some limit, it shows the memory allocation error message attached, and do not crash.
Tested in Windows 10 with QGIS 3.4.4, Master and 2.18.28 (OSGeo4W 64bits). This machine has 16GB of RAM.

Is this a regression compared to 2.18?

This looks very similar to the issue that I've been having (#21247). I thought it was a layout size, but it's probably more closely related to memory.

I think so Giovanni.
I've tested now in Linux, and here QGIS 3.4.4 has a similar behavior to QGIS 2.18.28 in Windows, that is, it throws a window with a warning
Trying to create image of 27165×27165 @ 300dpi resulted in a memory overflow. Please try a lower resolution or a smaller paper size.
and QGIS does not crash.
So, the crash and regression seems circumscribed to QGIS 3.4.4 and Master, in Windows machines.
Also in Linux, the warning message is showed when Composer needs somewhat above 1500 MB of memory. Could this limit be increased in 64bits versions?
