hi,
i have some threads and some mallocs. after a couple of malloc calls, i get a SIGSEGV from mallopt.
i compile the app (contains c and c++ files) with "gcc -g -O0 -lstdc++ -lpthread ..." (the code works under windows and multithreaded c++ libs, so there aren't any faults in the code)
the callstack looks like this:
Program received signal SIGSEGV, Segmentation fault. [Switching to Thread 49156 (LWP 11020)] 0x40186efa in mallopt () from /lib/libc.so.6 (gdb) where #0 0x40186efa in mallopt () from /lib/libc.so.6 #1 0x40186145 in malloc () from /lib/libc.so.6 #2 0x0804a3fd in Buffer::checkSpace(unsigned long) (this=0x8089458, writelen=4) at common/Buffer.cpp:143 #3 0x0804a507 in Buffer::addDWORD(unsigned long) (this=0x8089458, val=831) at common/Buffer.cpp:178 #4 0x0805bfc0 in SearchCommand::handle(NetBuffer*) (this=0x8069348, input=0x80893d0) at server/SearchCommand.cpp:79 #5 0x080591c7 in CommandThread::run() (this=0x8089408) at server/CommandThread.cpp:30 #6 0x0804ba37 in Thread::threadProc(void*) (param=0x8089408) at Thread.h:68 #7 0x400d3d53 in pthread_start_thread () from /lib/libpthread.so.0 #8 0x400d3d99 in pthread_start_thread_event () from /lib/libpthread.so.0
should i link to special threadsafe c++ libs (and if, how) ?
thanks
