On NixOS Linux distribution, we do not have FHS so, to allow Sublime to find pkexec, we load libredirect through LD_PRELOAD, replacing symbols related to opening files with our own. Recently, I have added support for dlopen but this broke Sublime:

When I try it on a simple dlopen example, it works, though:
void *cairo = dlopen("libcairo.so", RTLD_LAZY);
assert(dlerror() == NULL);
int (*cairo_version)(void);
*(void **) (&cairo_version) = dlsym(cairo, "cairo_version");
assert(dlerror() == NULL);
assert(cairo_version() > 0);
assert(dlclose(cairo) == 0);
Does Sublime do anything special with regards to dynamic loading?
