I think there is bug in the current strstr implementation. I initially found this in the codesourcery distribution and have recently reproduced it using newlib form CVS on both arm and x86 platforms. Here is the repro case: const char* s1 = "GL_OES_byte_coordinates GL_OES_compressed_paletted_texture GL_OES_fixed_point GL_OES_point_size_array GL_OES_point_sprite GL_OES_read_format GL_OES_single_precision GL_IMG_texture_compression_pvrtc GL_IMG_texture_env_enhanced_fixed_function GL_ARB_texture_env_combine GL_ARB_texture_env_dot3 GL_IMG_user_clip_planes GL_OES_matrix_get GL_IMG_vertex_program GL_EXT_multi_draw_arrays GL_OES_matrix_palette GL_OES_draw_texture "; const char* s2 = "GL_IMG_texture_compression_pvrtc"; const char* res = strstr(s1, s2); // crash in critical_factorization This bug seems to have been in newlib for a long time. It can be worked around by compiling with -Os and thereby disabling the strstr optimisations. -- sam clegg sam@ideaworks3d.com
