[BUGS] Bus error in formatting.c NUM_numpart_to_char (9.4.12, 9.6.3, sparc) - Mailing list pgsql-bugs

Hi,

I was trying to compile 9.4.12 on sparc from the debian source package in the pgdg repo, but it's failing multiple
regressiontests. One numeric test crashes the backend: 

LOG:  server process (PID 20659) was terminated by signal 10: Bus error
DETAIL:  Failed process was running: SELECT '' AS to_char_6,  to_char(val, 'FMS9999999999999999.999999999999999')
FROMnum_data;

It seems this issue was introduced in 9.4.9: 9.4.9, 9.4.10, 9.4.11 and 9.4.12 all crash at the same test at the same
linein formatting.c, but 9.4.8 builds successfully and passes all tests. It also seems that both NUM_numpart_to_char
andthe failing test have not been touched for, eh, decades, so the root cause must be somewhere else. 

The same issue is present in 9.6.3:

A potentially similar issue was introduced in 9.4.7 and resolved in 9.4.8:

https://www.postgresql.org/message-id/20160413094117.GC21485@msg.credativ.de

I can test patches or provide more information.

Best regards,
