#724: segfault in symbolGC tests on openbsd 5.0 with 4.7.0.3-stability

Type: defect | Status: reopened
Priority: major | Milestone: 4.9.0

-----------------------------+----------------------------------------------
Comment(by zbigniew):
It only happens one or twice every thousand tries. I ran it repeatedly
1000 times. Results are extremely inconsistent, except for how often it
occurs on average:
{{{
for i in $(seq 1 1000); do ./symbolgc-tests -:w; done > /dev/null
}}}
Results of nine runs of 1,000 invocations each:
- 1 segfault
- 1 non-procedure call
- 1 non-procedure call
- no errors
- 2 non-procedure calls
- 2 non-procedure calls
- 1 non-procedure call, 2 segfaults
- 2 non-procedure calls, 2 segfaults
- 2 segfaults
Non-procedure call looks as expected:
{{{
Error: call of non-procedure: -2882303761508213667
Call history:
