5504,Inconsistent sizes for struct rlimit,daniel.is.fischer,,"On my 32-bit system, I find

in `HsBaseConfig.h`. gcc says sizeof(rlim_t) = 4 and thus sizeof(struct rlimit) = 8.

Previously (7.0 and before), `get/setResourceLimit` allocated a 16-byte buffer and wrote/read the hard limit at an 8-byte offset, consistent with `HsBaseConfig.h` (but not with sys/resource.h), and apparently it worked (test resourceLimit used to pass and getting the limits returned the previously set values in a few tests for various resources).

Now they allocate 8 bytes and read/write the hard limit at a 4-byte offset, consistent with `sys/resource.h`, but inconsistent with `HsBaseConfig.h`, and resourceLimit fails, the same tests as above always returned `ResourceLimit (2^64-1)` for both, soft and hard limits. (The compiled ways of resourceLimit fail with invalid argument on setting.)",bug,closed,normal,,libraries/unix,7.3,duplicate,,,Linux,x86,None/Unknown,,,,,
