spiram_psram compilation error (IDFGH-1297)

[jeromeDms]

Dear all
I just updated esp-idf to the latest version and my project no longer compiles.
esp-idf version is v4.0-dev-728

I'm facing the following errors, and cannot find anything useful after searching.

CC build/esp32/spiram_psram.o
/esp32Dev/esp-idf/components/esp32/spiram_psram.c: In function 'psram_enable':

make: *** [component-esp32-build] Error 2

Anybody here having the same issue ?
Thanks to all

I saw that issue as well, I'll put a MR in with the fix. If you need a fix right now, in components/esp32/spiram_psram.c , in the function psram_enable, line 619, change

psram_io_t psram_io;

into

psram_io_t psram_io={0};

and the issue should be gone

Thanks, that did solve :-)
