pthread_mutex_lock.c:62: __pthread_mutex_lock: Assertion `mutex->__data.__owner == 0' failed. #34

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
I don't know how to reproduce.

go-magica-web.go:148 (my file) is :
if err := db.QueryRow("select getdate()").Scan(&timeNow); err != nil {

What is the expected output? What do you see instead?

go-magica-web: pthread_mutex_lock.c:62: __pthread_mutex_lock: Assertion 
`mutex->__data.__owner == 0' failed.

GoogleCodeExporter commented 9 years ago 
If you provide instructions to reproduce it here (on my pc), I will 
investigate. Otherwise I don't have enough information to go by (I am not Linux 
expert either, I use Windows myself).

Alternatively ask whatever questions you have. I might be able to give you some 
suggestions.

It looks like your program received signal:

SIGABRT: abort
PC=0xb775f424
signal arrived during cgo execution

because it does not use mutexes properly:

go-magica-web: pthread_mutex_lock.c:62: __pthread_mutex_lock: Assertion 
`mutex->__data.__owner == 0' failed.

Googling I find this: 
http://stackoverflow.com/questions/1105745/pthread-mutex-assertion-error

Go does not come with pthread_mutex_lock.c file. I suspect it is part of 
stdlibs on Linux.
