segfault when context switching in boost 1.76
romange opened this issue · comments
Sometimes I get segfault inside fiber library.
Below is a stacktrace that shows it
#0 boost::fibers::context::resume (this=0x0, lk=...) at libs/fiber/src/context.cpp:153
#1 0x00007ffff7fbabee in boost::fibers::scheduler::suspend (this=<optimized out>, lk=...) at libs/fiber/src/scheduler.cpp:314
#2 0x00007ffff7fb71dd in boost::fibers::context::suspend (this=this@entry=0xa6a4386ff00, lk=...) at libs/fiber/src/context.cpp:181

sorry, probably a problem with my scheduling algorithm.
