The repeated full ada bootstrap was successful at the same revision, using
identical flags and GNAT 5.4.0.
On the other hand, the failing build prints two warnings during the ada part:
g-debpoo.adb: In function ‘GNAT.DEBUG_POOLS.GET_SIZE’:
g-debpoo.adb:1418:8: warning: ‘SIZE_IN_STORAGE_ELEMENTS’ may be used
uninitialized in this function [-Wmaybe-uninitialized]
g-debpoo.ads:295:7: note: ‘SIZE_IN_STORAGE_ELEMENTS’ was declared here
and
g-comlin.adb: In function ‘GNAT.COMMAND_LINE.FIND_LONGEST_MATCHING_SWITCH’:
g-comlin.adb:583:8: warning: ‘PARAM’ may be used uninitialized in this function
[-Wmaybe-uninitialized]
g-comlin.adb:107:7: note: ‘PARAM’ was declared here
The error message read differently this time:
7.0.1 20170311 (experimental) (aarch64-linux-gnu) Storage_Error stack overflow
or erroneous memory access
