Describe the bug

thread 'main' panicked at 'prehook: Missed expected preemption! Clock_value: 29407230. Stepped forward 27577123 RCBs, but should have trapped at 17690825'

• [ ] a program hangs under hermit
• [x] hermit panics internally
• [ ] hermit runs the program but divergence (nondeterminism) occurs

To Reproduce Cannot share binary unfortunately. However it is linked against a basis library with quite some changes to standard glibc (lots of hooks). A simple program works. So I suspect that library to be the problem.

Expected behavior Program executes successfully.
