Extended Description
Created an attachment (id=781) 3 sac source files It would appear that module support for the cuda backend is broken. The testcase in this bug report uses a very simple with loop that has been verified as cuderisable. The tarboll contains 3 sac source files. A) One single program with a call to an inlined function in the same source file. B) One module with an inlined function C) One separate program that calls the above module Program A compiles and runs with "-t cuda". B and C compile with "-t cuda" but seqfault at runtime. All tests were run with an up-to-date product compiler. This is the backtrace from gdb: #0 0x00007fffeec44bda in std::_Rb_tree_decrement(std::_Rb_tree_node_base*) () from /usr/lib/libstdc++.so.6 #1 0x00007ffff1f86366 in ??
