[Mono-dev] Assertion at mini-arm.c:5559, condition `IS_LDR_PC (code_ptr [0])' not met

[Bassam Tabbara]

Hello,

We are seeing the following on ARM devices. Running mono built from the 2-10 branch. Any ideas for where to start here?

invalid code stream, instruction before IMT value is not a LDC in mono_arch_find_imt_method() (code 0x40be8868 value 0: 0xe1a06000 -1: 0xe591f028 -2: 0xe1a0e00f)
* Assertion at mini-arm.c:5559, condition `IS_LDR_PC (code_ptr [0])' not met

Debug info from gdb:


=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
