Hi Daniel,
I'm using libcurl 7.29 and I've tested on Android 2.2 and 4.1 (our target requirement is 2.2 - API Level 8)
I also tried isolating the call to curl with a mutex but without success either.

It's hard to pinpoint the problem because we still haven't been able to get a stacktrace out of ndk-gdb.

Thanks a lot.

Using which libcurl version? Using what Android version?

I found this bug report from Mozilla "Bionic domain name functions are not thread-safe on pre-3.0 Android":
https://bugzilla.mozilla.org/show_bug.cgi?id=687367 (also blogged about here:
http://boomswaggerboom.wordpress.com/2011/12/18/improving-dns-performance-in-firefox-for-android/)

It mentions the fopen from stdio to be a reason, and the stacktrace from the libcurl posting from 2007 also evidently shows fopen...

Any chance that's what you're experiencing?
