Update of bug #21160 (project freeciv):
Status: None => Confirmed
Operating System: Microsoft Windows => Any
Summary: Stack overflow if "Team pooled reserch" is disabled
with some human team players => Stack overflow if "Team pooled research" is
disabled with some human team players
_______________________________________________________
Follow-up Comment #3:
Reproduced with 2.4.0 on Linux. I get a segmentation fault rather than
explicit stack overflow, but it's clear we have some recursion gone mad.
Head of S2_4 behaves similarly.
