Got this problem when running my compiled wxformbuilder:
To debug the issue, valgrind is our friend in this case.
For example, when running it with valgrind it shows a lot of memory leaks (apparently some issues in wxWidgets):

Debugging with GDB gives:
***MEMORY-ERROR***: wxformbuilder[19377]: GSlice: assertion failed: aligned_memory == (gpointer) addr
Aborted (core dumped)
The workaround is to embed G_SLICE=always-malloc when invoking the command-line, e.g:
G_SLICE=always-malloc ./wxformbuilder
According to the GLib documentation:
G_SLICE=always-malloc ./wxformbuilder
According to the GLib documentation:
always-malloc:This will cause all slices allocated through g_slice_alloc() and released by g_slice_free1() to be actually allocated via direct calls to g_malloc() and g_free(). This is most useful for memory checkers and similar programs that use Boehm GC alike algorithms to produce more accurate results. It can also be in conjunction with debugging features of the system's malloc() implementation such as glibc's MALLOC_CHECK_=2 to debug erroneous slice allocation code, although debug-blocks is usually a better suited debugging tool.
To debug the issue, valgrind is our friend in this case.
For example, when running it with valgrind it shows a lot of memory leaks (apparently some issues in wxWidgets):
