After fetching the latest major update to libmudflap, I tried
my build and has a showstopper.
When running with
export MUDFLAP_OPTIONS="-trace-calls -verbose-trace"
my program stops (hangs forever) at this point:
mf(1024): pthread_create
mf: reentrancy detected in `malloc'
However, if I run with
export MUDFLAP_OPTIONS="-trace-calls"
my programs seems to run to completion but hangs at exit time in
mf(1026): __mfwrap_strlen
mf: erroneous reentrancy detected in `__mf_check'
Based on other tracing I find that the above error was logged
just after my thread function executed the final "return (NULL)",
and I do count not relate the above strlen() to my code.
I will investigate further this weekend.
